Hello folks,
Prompted by Ashley's proposal for Category class, I came up with the following
module, which gives a summary of the overloading situation in the base package.
Maybe it can help people find their way through all the available names...
Failing that it surely was fun to come up with. :)

Similarly:
instance Arrow a = Applicative (a r) where
return a = pure (const a)
a * b = pure (\(f,x) - f x) . a b
