Re: {-# LINE 100 "Foo.hs #-} vs. # 100 "Foo.hs"

With all this talk of preprocessor generated information and whatnot, I am reminded of a paper I read not too long ago but can't seem to find anymore about a dedicated pre-processor for haskell based on the C preprocessor but made to deal with haskell constructs a bit more sanely.

This was me... http://www.cl.cam.ac.uk/~kw217/research/papers.html#Wansbrough99:Macros There wasn't sufficient interest, and no one has offered to implement it. I think people are mostly happy using CPP, and the hassle of writing a `decent' macro preprocessor isn't worth it. You may find some of the ideas in the paper useful, though. --KW 8-)
