Comment (by osa1):

 I don't have any progress yet but I just wanted to say that passing
 `HsModule`(or some fields of it) around may not be very bad, and GHC is
 already doing similar things. For example, `DataCon` has a `[HsSrcBang]`
 field which is carried around until Cmm(or maybe even backend code
 generation) stage I think. `HsSrcBang` is this:

 {{{#!haskell
 data HsSrcBang =
   HsSrcBang (Maybe SourceText)
             SrcUnpackedness
             SrcStrictness
 }}}

 Some(maybe all) parts of this are coming from the parser.
