Which extensions are you using that are not Haskell 98? I would be very
interested to know what users would generally require from a refactorer.

I agree with Neil, AST editors are generally ugly and hard to use. There
is also the problem of laying out Haskell code. Everyone uses their own
layout style and pretty printing ASTs is generally a bad thing to do in
this context.
