Re: #4189: Add (<.>) operator (generalizing (.) to Functor)

Well, blackbirdA wasn't entirely a serious contender, I'd still prefer a word name rather than an operator. Note, that you naming as an infix operator a 3 parameter function, with the intention that the third parameter will generally be elided by programming in a point-free style. I don't think there are any other examples in Prelude plus Control.Monad / Applicative / Category / Arrow of this. Many of the operators expand to three parameters for the function instance, but their general signature is still two params plus result. (<.>) :: Functor f => (b -> c) -> (a -> f b) -> a -> f c f <.> g = fmap f . g
