How about a ghci prompt? You can reload using <colon> <ret>

Indeed, it has never been done.  I'm not entirely convinced it's
decidable.  But that hasn't stopped anybody from writing parsers for
the commonly used subset of haskell!  Also, highlighting normally does
not require a full parser, just a lexer (which is easy).  (Beschers'
experimental Emacs mode actually highlights type errors...)
