[...] You use unqualified and implicit imports. That is according to the PVP you would need to use tight version bounds like "containers >=0.4.0 && <0.5.0.1", but you don't. That is, your package does not conform to the PVP. [...]
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 else.
