Re: Thinking about what's missing in our library coverage

But the CPP that GHC supports is different (albeit less good) than cpphs. So if you want to support the extension as it is currently defined/used, you should just shell out to cpp like GHC does.

Shelling out to CPP is not much help if the executable that uses haskell-src-exts is running on a machine that does not have a C pre- processor installed (or if it is not configured to be found easily). Regards, Malcolm
