Proposal 0: ----------------
Do nothing
Seeing as this has come up a bunch of times, -1 - as we clearly need to do *something*. Proposal 1:
---------------- Add no new code, but document Data.Either to mention how to use `left` and (+++) from Control.Arrow
+1
Proposal 2: ---------------- Document Control.Arrow to exemplify the (->) instance usage.
More examples is in general a good idea - I see no harm in this. +1
Proposal 3: ----------------
Proposal 4:
----------------
Proposal 5: ----------------
== Proposal 4, using the mapEither name instead.
Indifferent on these.
Proposal 6: ----------------
Implement mapRight in Data.Either
6a) ... as (b -> c) -> Either a b -> Either a c 6b) ... as fmap
-1 on this, as we don't have 'mapJust' and Functor is hardly an esoteric type class. Proposal 7:
----------------
Don't implement mapRight, but include documentation in Data.Either stating that it is just fmap.
Again, more documentation is almost always a good thing. +1 Proposal 8:
----------------
Bring bifunctors to base.
-1, and seems at ends with the split base proposals. I don't see much value in growing base a whole lot more. I'm probably opening a whole 'nother can of worms. Apologies ;)
