o_O Dumb question: Can somebody please explain why this doesn't
conform to the PVP? I have a very hard time reading that out of
http://www.haskell.org/haskellwiki/Package_versioning_policy. Perhaps
I'm looking at the wrong document or this interpretation is just
wishful thinking...

Regarding upper bounds: I never understood what their advantage should
be, IMHO they only lead to a version hell where you can't compile your
stuff anymore *only* because of the bounds, not because of anything
