Surprising behavior with CPP extension
The CPP language extension performs macro substitutions in Haskell comments. I see why it does but it seems like eliding the comments before pre-processing would be less surprising. Eg. compiling:
{-# LANGUAGE CPP -#}
-- | Some folder foo/bar/*
gives the error:
error: unterminated comment
-- | Some folder foo/bar/*
because the /*
in the comment is interpreted as starting a C comment.
