While we're on the topic, is there any reason why ZipList is a data type instead of a newtype? Is the extra bottom actually necessary for the Applicative semantics? If not, then I'd suggest changing it to a newtype in order to remove the extra indirection.
It is actually a newtype, and has been at least since base-3.0.3.1 (the oldest 'base' available on hackage). -- Roman I. Cheplyaka :: http://ro-che.info/
