Re: Proposal: flipped fmap in base (again)

I am using `for` https://hackage.haskell.org/package/Agda-2.5.2/docs/Agda-Utils-Functor.html and I think taking `for` for Applicative was name theft. On 19.02.2017 23:52, Elliot Cameron wrote:

Could we instead have "ffor" which can be used prefix or infix and avoids the operator soup problem?

I'm weakly +1 on this proposal. In my experience

foo <&> \x -> ...

works out as a nice idiom because it avoids having to parenthesize the lambda unlike the usual <$> convention.

For me, I can just make lens re-export the Data.Functor version on newer GHCs.

module Data.Functor, infixl 1, and should not be in prelude.
