    Remove support for (**{ ... code ... }).  This was introduced in
    Perl 5.37.8 along with a single-splat version.  The double-splat
    version was removed without deprecation in Perl 5.37.9, so it is
    being removed without deprecation here as well, per my stated policy
    about development functionality.  The single-splat version still
    exists (and is documented) in Perl 5.37.9, and in this package.

    Add support for code in optimized regex, a.k.a. (*{...}).  This
    involved making the recognition of backtracking control more
    specific, since it also uses (?*...).
    If (*{...}) and (**{...}) are removed from Perl before Perl 5.38.0,
    support for them will be removed from this package.

    Add width(), which returns the number of characters matched. Note
    that an indefinite upper boumd is represented as IEEE 754 Inf if
    that appears to be supported; otherwise by a singleton object
    overloaded to allow stringification, numification, and numeric
    tests.
    Use width() to enhance the detection of variable-width look-behinds.

    Require PPI 1.238 for postfix deref support, and recode the
    postfix deref logic in terms of 1.238's functionality.
    Parse '@{[ ... ]}' as code, not interpolation.  This is more in line
    with what it actually represents, and allows correct versioning of
    postfix dereferences.  But is is an incompatible change.

    Look-behinds quantified longer than 255 characters are an error, and

    Try to get correct line number in derived PPI. This is done by
    injecting "
  " as needed. The initial #line directive becomes "#line
    2", but is suppressed if I need to generate line 1.
    Improve normalization of content for ppi(). This involves the
    un-bracketing of things like ${foo}.
    Deprecate new() argument postderef. At this stage it is only
    documented as deprecated. In the first release after October 1 2020
    it will warn on the first use. Eventually it will be retracted, and
    postfix dereferences will always be recognized. This is the default

    Add index_locations option to PPIx::Regexp->new(). This defaults to
    true if the regexp is specified as a PPI::Element object. The
    locations are consistent with the containing PPI::Document.
    Add methods location(), column_number(), line_number(),
    logical_filename(), logical_line_number(), and
    visual_column_number() to PPIx::Regexp::Element. All return undef if
    the locations could not be determined.
    Add method statement() to PPIx::Regexp::Element. This returns the
    PPI statement containing the regexp element, or nothing if none.
    Add method is_matcher() to PPIx::Regexp::Element. This classifies
    objects as to whether they actually match something in the target
    string. Possible returns are true (they do), false but defined (they
    do not) and undef (no clue).
    Add methods first_token() and last_token() to PPIx::Regexp::Node.

    PPI::Token::Regexp::Transliterate
    Support proper version for qr'\N{name}'. Until 5.29.10 this
    construction failed to parse because it did not interpolate. But
    PPIx::Regexp blithely ignored this detail. As of 5.29.10, something
    like m'\N{LATIN CAPITAL LETTER L}' matches identically to m'L'. So I
    implemented introduction as of that version.

    \o{} should be an error
    \o{ non-octal } should be an error under "use re 'strict'"
    Support wildcard Unicode property values. These were added in
    5.29.9.
    Add eg/find-variable-length-lookarounds
    Add convenience method extract_regexps(). This is a static method
    on PPIx::Regexp that takes as its argument a PPI::Document and
    manufactures PPIx::Regexp objects out of anything that parses to a
    regexp of some sort.
    Don't run illegal character tests before Perl 5.18 unless we're
    author testing, because they are noisy. I think the issue is not the
    Perl version per se, but the version of Unicode; Perl5180delta says
    it shipped with Unicode 6.2.

    Only standalone graphemes and non-characters allowed as delimiters
    starting with Perl 5.29.0.
    Non-ASCII delimiters started working in 5.8.3, so that is what
    perl_version_introduced() returns for them.
    Collateral with all this, accept word characters as delimiters, but
    only with at least one space between the operator and the expression
  - - that is, 'qr xyx' is OK, but 'qrxyx' is not.

    \N{} now parses as the unknown token, not NoOp, regardless of the
    setting of 'use re qw< strict >;'. \N{} became unconditionally fatal
    in 5.28.0 (5.27.1, actually). The policy when the parse changes is
    to use the most-modern parse. Hence this change.
    As a side effect of this, the unknown token's explain() method now
    returns something -- normally the associated error.
    Add method remove_insignificant(). If the invocant isa Node, this
    returns a clone of the invocant with non-significant elements
    removed. Otherwise it returns either the invocant or nothing.

    Further deprecate string (versus regexp) parsing. The first use of
    the 'parse' argument to new() will result in a warning.  If the

    PPIx::QuoteLike.

    Prefer /[0-9]/ over /\d/ for numeric checks. The latter can match
    non-ASCII digits.
    Explain the negated POSIX character classes. Also tweak some of the
    asserted explanations -- mostly for readability and parallel
    construction with the negated explanations, but it turns out
    [[:digit:]] is NOT equivalent to [0-9].

    Allow ->asserts( 'a*' ). This modification actually allows wild
    cards in asserts() on all match semantic modifiers, but it is
    probably only useful in the case of 'a*', because that is the only
    one that can be doubled.
    Explain grouping structure as 'Grouping', not 'Capture or grouping'.
    Caret modifier was not turning off /n. This was complicated by the
    fact that (?^) was introduced in 5.13.6, but (?n) was not introduced
    until 5.21.8. The solution was to include -n in the expansion of the
    caret if and only if /n had been seen in the scope of the caret.

    which was deprecated in 5.27.8. No actual change in output yet,
    since deprecation is not tracked, but the perl_version_removed()
    logic is there.
    Add next_element() and kin. These are analogous to next_sibling()
    and kin, but will cross over from content proper into structure
    (beginning and end delimiters, etc) and vice versa.
    Correct requirements_for_perl() for impossible regular expression.
    It now returns '! $]' when the components of the regexp are valid, but
    none are valid under any specific version of Perl. It used to think all
    Perls were OK when this happened.

    After '.', Unicode classes, and bracketed classes (including extended)
    they are still legal.
    Make /{/ an error
    Perl fails to parse the above, because once it sees the '{' it wants
    to find one of the extended boundary assertions (like {wb}), and
    declares an error when it does not. So we check for this and rebless the
    curly into an unknown token, not a literal.

    Parse bracketed substitution with embedded comment. This is something
    like s{foo}
  [#]{bar}
  {baz} which is equivalent to s/foo/baz/. PPI
    gets this wrong, and we're not smart enough to fix up the PPI parse,
    but if given this as text, we now parse it correctly.
    We now recognize postfix dereferences by default, since Perl does
    beginning with 5.24. In other words, default new() argument
    'postderef' to true.
    Unterminated substitutions (i.e. 's//') should no longer cause an
    exception. Instead they parse as an unknown token.

    The perlop docs say these nest with each other. Playing with Perl
    suggests that \U, \L and \F supersede each other, but thet they as a

    Parse \U and friends as meta-characters inside \Q...
    This turns out to be what Perl itself does, as shown by
    $ perl -E 'say qr{\Qoo}'

    Clear error when lexer identifies unknown token. Those who peruse the
    changes in this release will see that a bunch of refactoring was
    done as part of this.

    Parse white space inside bracketed character classes inside extended
    bracketed character classes (whew!) as literals, except for the
    space character itself and the horizontal tab. This tracks the
    corresponding change in Perl 5.23.4. This will be reverted if the
    corresponding Perl change does not make it into 5.24.0.

    Beginning with version 0.035, PPIx::Regexp was incorrectly reporting
    the sense of modifiers when the same token both asserted and negated
    modifiers (e.g. '(?x-i:...)'). This release should correct the
    problem.
    Document policy when Perl changes in such a way that the proper parse
    for a regular expression changes. In this case the more modern parse
    is preferred.

    Report error rather than failing when parsing a string consisting
    wholly of white space.

    Group types were not being recognized if they contained the delimiter
    character for the regexp (e.g. in qr<(?\<foo)> the look-behind
    assertion was not recognized as such).
    Correct mis-parse of ' s///'. Leading white space is supposed to be
    acceptable, but the leading whitespace token caused
    PPIx::Regexp::Lexer not to recognize the substitution as such.
    Tokenizer was failing when the string to be parsed was so bad it was
    trying to return the whole thing as a single
    PPIx::Regexp::Token::Unknown.
    PPIx::Regexp::Dumper now displays a message if a structure is missing
    its end delimiter.

    RT 107331 Produce parse error in the presence of trailing cruft.
    Thanks to Klaus Rindfrey for catching this.
    The tokenizer now does a preliminary scan for delimiting brackets
    and modifiers. Anything after the modifiers except for white space
    is now made into a PPIx::Regexp::Token::Unknown, resulting in a
    parse failure being reported. The previous implementation simply
    assumed a valid expression, and in the case of the expression in the
    ticket blithely mismatched the delimiters and returned a parse
    without failures, but which was manifestly bogus.
    Tweak documentation in PPIx::Regexp.

    Accept non-ASCII whitespace under /x. The Whitespace object can be
    multiple characters; the perl_version_introduced() becomes
    '5.021001' if any of them is a code point above 127.
    The perl_version_removed() method now returns '5.021001' when called
    on a PPIx::Regexp object produced by parsing '?foo?' (match once
    without explicit 'm'). The object produced by parsing 'm?foo?' still
    returns the minimum Perl version.

    Do not parse unadorned parentheses as capture groups when /n is in
    effect. Instead, they are parsed as PPIx::Regexp::Structure. Named
    captures appear to be unaffected by /n.
    Made a verbose dump a little more so. Specifically, dump
    max_capture_group where relevant, and display dumped values a bit
    more informatively.

    Recognize nested subscripts in interpolation.
    Thanks to Andy Lester for finding this, which actually manifested in
    Perl-Critic-Policy-Variables-ProhibitUnusedVarsStricter. The problem is
    that the actual heuristics for finding the end of an interpolation are
    undocumented, and I missed this rather-obvious case.

    Make {foo} into an unknown token (and therefore an error. This
    applies to {anything}, where 'anything' is anything bur 'gcb',
    'wb', or 'sb'.

    Handle the boundary assertions introduced in Perl 5.21.9: '{gcb}'
    (grapheme cluster boundary), '{wb}' (word boundary), '{sb}'
    (sentence boundary), and the corresponding '\B{...}' constructions.
    Similar-looking things like '{foo}' are not recognized as
    assertions, and end up being literals.  This is less general than I
    usually make things, but was done against the possibility that
    (e.g.) '{foo}' might be introduced later, requiring
    perl_version_released() to return a different number. Any of these
    retracted prior to Perl 5.22.0 will simply be removed from
    PPIx::Regexp.

    Correctly mark the replacement portion of s///ee as code. Prior to
    this release it was parsed as though no /e were present.
    Make available the number of times a given modifier is asserted
    (except for the match semantics modifiers which get handled
    differently). See PPIx::Regexp::Token::Modifier->asserted() and
    PPIx::Regexp::Tokenizer->modifier() for details.
