These PLIST files have been autogenerated by mk/haskell.mk using
HS_UPDATE_PLIST=yes during a bulk build. They will help to track changes
to the packages. The Haskell packages didn't have PLIST files because
their paths contained package hashes. These hashes are now determined by
mk/haskell.mk, which makes it easy to generate easy to read PLIST files.
Contravariant functors, sometimes referred to colloquially as
cofunctor, even though the dual of a functor is just a functor. As
with functor the definition of contravariant for a given ADT is
unambiguous.
