ghc-lens-5.1-bp154.1.15

- Update lens to version 5.1 revision 1.
  Upstream has revised the Cabal build instructions on Hackage.

- Update lens to version 5.1.
  5.1 [2021.11.15]
  - ---------------
  * Allow building with GHC 9.2.
  * Drop support for GHC 7.10 and older.
  * The type of `_ConP` in `Language.Haskell.TH.Lens` is now
    `Prism' Pat (Name, [Type], [Pat])` instead of `Prism' Pat (Name, [Pat])`
    when building with `template-haskell-2.18` or later.
  * Define `_CharTyLit` in `Language.Haskell.TH.Lens` when building with
    `template-haskell-2.18` or later.
  * Add `Prefixed` and `Suffixed` classes to `Control.Lens.Prism`, which provide
    `prefixed` and `suffixed` prisms for prefixes and suffixes of sequence types.
    These classes generalize the `prefixed` and `suffixed` functions in
    `Data.List.Lens`, which were previously top-level functions. In addition to
    providing `Prefixed` and `Suffixed` instances for lists, instances for `Text`
    and `ByteString` types are also provided.
    At present, `Prefixed` and `Suffixed` are re-exported from `Data.List.Lens`
    for backwards compatibility. This may change in a future version of `lens`,
    however.
  * Add a `traversal` function to `Control.Lens.Traversal`. This function, aside
    from acting as a `Traversal` counterpart to the `lens` and `prism` functions,
    provides documentation on how to define `Traversal`s.
  * Add a `matching'` function to `Control.Lens.Prism`. `matching'` is like
    `matching`, but with a slightly more general type signature that allows it to
    work with combinations of `Lens`es, `Prism`s, and `Traversal`s.

- Update lens to version 5.0.1 revision 2.

- Update lens to version 5.0.1 revision 1.
  Upstream has revised the Cabal build instructions on Hackage.

- Update lens to version 5.0.1.
  5.0.1 [2021.02.24]
  - -----------------
  * Fix a bug in which `makeLenses` could produce ill kinded optics for
    poly-kinded datatypes in certain situations.

- Update lens to version 5.
  5 [2021.02.17]
  - -------------
  * Support building with GHC 9.0.
  * Remove the `Swapped` type class in favor of `Swap` from the `assoc` package.
  * Remove the `Strict` type class in favor of `Strict` from the `strict` package.
    The `swapped`, `strict` and `lazy` isomorphisms are now defined using "new" type classes.
    Users which define own instances of old type classes are advised to
    define instances of the new ones.
    ```haskell
    import qualified Data.Bifunctor.Swap as Swap
    import qualified Control.Lens        as Lens
    instance Swap.Swap MyType where
    swap = ...
    [#]if !MIN_VERSION_lens(4,20,0)
    instance Lens.Swapped MyType where
    swapped = iso Swap.swap Swap.swap
    [#]endif
    ```
  * The `FunctorWithIndex`, `FoldableWithIndex` and `TraversableWithIndex` type classes
    have been migrated to a new package,
    [`indexed-traversable`](https://hackage.haskell.org/package/indexed-traversable).
    The `imapped`, `ifolded` and `itraversed` methods are now top-level functions.
    If you are not defining these methods in your instances,
    you don't need to change your definitions.
    Beware: the `optics-core` package (versions <0.4) defines similar classes,
    and will also migrate to use `indexed-traversable` classes. Therefore, you
    might get duplicate instance errors if your package defines both.
    If you define your own `FunctorWithIndex` etc. instances,
    we recommend that you depend directly on the `indexed-traversable` package.
    If you want to continue support `lens-4` users, you may write
    ```haskell
  - - from indexed-traversable
    import Data.Functor.WithIndex
  - - from lens
    import qualified Control.Lens as L
  - - your (indexed) container
    data MySeq a = ...
  - - indexed-traversable instance
    instance FunctorWithIndex     Int MySeq where imap = ...
    instance FoldableWithIndex    Int MySeq where ifoldMap = ...
    instance TraversableWithIndex Int MySeq where itraverse = ...
  - - lens <5 instance, note the !
    [#]if !MIN_VERSION_lens(5,0,0)
    instance L.FunctorWithIndex     Int MySeq where imap = imap
    instance L.FoldableWithIndex    Int MySeq where ifoldMap = ifoldMap
    instance L.TraversableWithIndex Int MySeq where itraverse = itraverse
    [#]endif
    ```
    In other words, always provide `indexed-traversable` instances.
    If your package depends on `lens` and allows `lens-4`,
    you should additionally provide instances for `lens-4` type classes
    that can reuse the `indexed-traversable` instances.
  * Make the functions in `Control.Lens.TH` work more robustly with poly-kinded
    data types. This can cause a breaking change under certain situations:
  * TH-generated optics for poly-kinded data types are now much more likely to
    mention kind variables in their definitions, which will require enabling
    the `PolyKinds` extension at use sites in order to typecheck.
  * Because TH-generated optics now quantify more kind variables than they did
    previously, this can affect the order of visible type applications.
  * Generalize the types of `generic` and `generic1` to allow type-changing
    updates. If you wish to use the old, more restricted types of these
    functions, use `simple . generic` or `simple . generic1` instead.
  * Add `Control.Lens.Profunctor` with conversion functions to and from
    profunctor optic representation.
  * Add `Control.Lens.Review.reviewing`, which is like `review` but with a more
    polymorphic type.
  * Mark `Control.Lens.Equality` as Trustworthy.
  * The build-type has been changed from `Custom` to `Simple`.
    To achieve this, the `doctests` test suite has been removed in favor of using [`cabal-docspec`](https://github.com/phadej/cabal-extras/tree/master/cabal-docspec) to run the doctests.
  * Use `alterF` in `At (HashMap k)` instance implementation.
  * Use `alterF` in `At` and `Contains` instances for `Set`, `IntSet`, and
    `HashSet`.
  * Avoid re-inserting keys already present in `ix` for `Set`, `IntSet`,
    and `HashSet`. For `Set` and `HashSet`, this changes the semantics
    slightly; if the user-supplied key is `==` to one already present in
    the set, then the latter will not be replaced in the result.
  * Consume `()` values lazily in `Control.Lens.At`.

- Update lens to version 4.19.2.
  4.19.2 [2020.04.15]
  - ------------------
  * Remove the test suite's dependency on `test-framework-th`.

- Update lens to version 4.19.1.
  4.19.1 [2020.02.13]
  - ------------------
  * Fix a bug introduced in 4.19 where using `_TupE` to `preview` a value would
    always fail.

- Update lens to version 4.19.
  4.19 [2020.02.03]
  - ----------------
  * Support building with GHC 8.10.
  * The types of `_TupE` and `_UnboxedTupE` are now `Prism' Exp [Maybe Exp]`
    when built against `template-haskell-2.16` or later to reflect the new
    types of `TupE` and `UnboxedTupE`.
  * Add `_ForallVisT` and `_BytesPrimL` prisms when building against
    `template-haskell-2.16` or later.
  * Make `<>~` and `<>=` and their `<op` and `<<op` state variants require only
    `Semigroup`, not `Monoid`.
  * Add `{Functor,Foldable,Traversable}WithIndex` instances for
    `Control.Applicative.Const` and `Data.Functor.Constant.Constant`.

- Drop obsolete group attributes.

- Update lens to version 4.18.1.
  4.18.1 [2019.09.13]
  - ------------------
  * Remove the use of `cpp-options: -traditional`. This should be unnecessary
    on all versions of GHC that `lens` supports, as modern GHCs already use
    `-traditional` internally during preprocessing. More critically, the use
    of `cpp-options: -traditional` breaks profiling builds on GHC 8.8
    (see https://gitlab.haskell.org/ghc/ghc/issues/17185).

- Update lens to version 4.18.
  Upstream has edited the change log file since the last release in
