Just a note – the storable syntax tree you're looking for is called  
"a .hs file".  You just want a nice interface to your Haskell parser  
so that said syntax transformers can work easily.

You might want to look at how HaRe does it.  I believe using  
Programatica at the moment, because it's the only one that preserves  
comments and code layout.
