This package provides a way to persist data from compile-time to runtime by
producing Template Haskell expressions that evaluate to particular values.
For example, if you have a value 'Just 1', then 'toExp (Just 1)' will produce
the /expression/ '[e| Just 1 |]', which can be used in a splice. For a more
direct example, here’s what that looks like without the quasiquote notation:
>>> toExp (Just 1) AppE (ConE GHC.Base.Just) (LitE (IntegerL 1))
This is done by using a typeclass, 'ToExp', that can be automatically derived
for types that have a 'Generic' instance.
