I’d expect fromEither to be
Either a b -> (a-> c )-> (b-> c) -> c
Nothing about the name fromEither is suggestive of the Either a a type

Regardless of having a more abstract version, I'm +1 on Jon's suggestion, and those names. fromEither is something I have reached for many many times and been surprised it's not within arms reach.

I’m strongly for these:
