Apart from that, this package (and thus the others, with a few #ifdef's) would work with Hugs. How about eliminating the above overlaps?
I don't have Hugs installed, so could you try porting the regex-base in the HEAD of http://darcs.haskell.org/packages/regex-unstable/regex-base that I just updated? This creates 4 newtypes in the RegexLike module that are used in RegexContext to disambiguate the semantics and remove the overlap that Hugs complains about: newtype AllSubmatches f b = AllSubmatches {getAllSubmatches :: (f b)} newtype AllTextSubmatches f b = AllTextSubmatches (f b) newtype AllMatches f b = AllMatches (f b) newtype AllTextMatches f b = AllTextMatches (f b) This has another benefit, in that I don't have to choose whether the result type of [b] is the submatches or all the whole matches, since I now use newtypes to provide both flavors. And most things are now available as either a list or an (Array Int). And [[b]] is now available in all 4 list/array flavors. -- Chris
