Personally, I'd be all for just moving Foldable (and Traversable) into the Prelude and retiring the monomorphic versions of the functions they supply. Both abstractions have born the test of time, and its hard to even envision Haskell without them at this point.

I'm somewhat leery that we coud get this proposal past the "but it makes it harder to introduce people to Haskell" backlash, but I'd wholeheartedly support it.

A hearty +1 for this. -- John Wiegley FP Complete Haskell tools, training and consulting http://fpcomplete.com johnw on #haskell/irc.freenode.net
