* Maintaining Haskell98 compatability. Keep it simple. (See regex-posix's mistakes here)

At the risk of resurrecting an old (albeit unfinished) thread, I've just discovered that FGL is actually not Haskell98 compatible anyway, as it utilised the following extensions: MultiParamTypeClasses, OverlappingInstances, FlexibleInstances, ScopedTypeVariables Whether it needs all of these is a different story (ScopedTypeVariables seems to be there just because some type sigs have a forall in them), but it does indeed have them and is thus Haskell98 compatible. So this argument isn't valid ;-) -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
