yay!-) i hope that the haddock-independent part (parsing, preserving,
and accessing comments) becomes part of the GHC API in a form 
that would fix trac ticket #1886, then we could finally start writing 
(ghc) haskell source-to-source transformations without losing 
pragmas or comments! 

losing layout would still be a pain, but that could be dealt with
later - at least the code would remain functional under some
form of (pretty . id . parse).

please keep us posted about your experiments,
