A possible route to get a "real-world" (i.e. well debugged and
complete H98) module AST would be:
* Throw all files needed by GHC's parser together in a subdir.
* Remove everything GHC-specific, e.g. lexing the .hi stuff.
* Track changes to the relevant sources in the CVS in AST. This
should be very tedious, because those parts of GHC are quite
stable by now.
The only tricky point is dealing correctly with infix ops in the
presence of the module system. Any *easy* suggestions for this?
Perhaps if I have some spare time... (Hmmm, not very probable at the
moment, the weather in Munich is too nice... :-) But I wouldn't mind
if somebody else volunteered.
Cheers,
Sven
