Hi,
I find it strange that right now almost every Haskell program directly or indirectly (through FPTOOLS) depends on CPP, yet there is no effort to replace CPP with something better or standardize its usage in Haskell. According to the following document, and my own limited experience in reading Haskell code, CPP is the most frequently used extension: http://hackage.haskell.org/trac/haskell-prime/wiki/HaskellExtensions I think that if we accepted that CPP was part of the language, we could then place some restrictions on its use to facilitate easier parsing. Here are some suggestions, off the top of my head:
see this paper for some interesting work on the subject. http://citeseer.ist.psu.edu/wansbrough99macros.html there would be no need to integrate it with compilers, it could be a stand-alone tool, like hsc2hs. John -- John Meacham - ⑆repetae.net⑆john⑈
