[Template-haskell] TH preprocessing

[Simon Peyton-Jones]

Not at present.  It's actually a little trickier than it looks, because
the post-type-checked program (with the splices expanded) has dictionary
stuff floating around, and it's not entirely straightforward to convert
it back to vanilla source Haskell.

You're right it would be useful.  I think it's feasible with a bit of
work.  I'd be willing to help anyone who wanted to undertake it.

| Hello,
| 
| is there a program which takes a Haskell source file, compiles it with
| -ddump-splices, replaces the splices in the source file with the
dumped code
| and outputs the resulting file?  I'd like such a tool since I think it
would
| it make possible to use TH with Hugs.  You would preprocess each file
with
| this program and feed Hugs with the resulting files.
