Well, HaRe -- the Haskell refactorer -- offers a full API for building
transformations and refactorings for the full Haskell 98 standard.


A new release will hopefully be released very soon (even in the next
few days) which will be compatible with ghc-6.6.1.
The releases on our refactoring page currently only work with GHC-6.4.*.

HaRe also uses the GHC API and type checker, with parts of the HaRe API
extended to retrieve type information from GHC on abritrary expressions
and functions.

Kind regards,
