Hi all, I was wondering if anyone knew the rationale behind naming the module Data.Functor instead of the (seemingly) more natural Control.Functor.

I'm not sure if it answers your question, but it goes along with Applicative living under the Data, not Control hierarchy.

Actually there is Control.Applicative, but Data.Foldable and Data.Traversable. I guess the answer is that functors include control-like things like monads and applicative functors, but also data-like things like trees and maps.
