Re: rfc: Additions to Data.Either (take 2)

thanks joão for the write-up.

Proposal 1: Add no new code, but document Data.Either to mention how to use `left` and (+++) from Control.Arrow

(+1 for documentation, but that's not what that proposal is about)

Proposal 2: Document Control.Arrow to exemplify the (->) instance usage.

+1

Proposal 7: Don't implement mapRight, but include documentation in Data.Either stating that it is just fmap.

+1

Proposal 8: Bring bifunctors to base.

(my favorite by far) +1 all others i am ignorant about. cheers, tobias florek
