if "Either" types are typically used for error handling, why isn't there a version with more semantic method names than "left" and "right"?
I would argue that "left" and "right" carry too much semantic information already, for a type that's meant to be generic.

That's exactly my point - that it would be nice to have something more purpose-specific. I, for one, get lost with lefts and rights in this specific use case of returning "either result or error".

So the problem is, if you write an additional version of Either which is isomorphic, but with non-generic names, then third-party generic code needs to support its interface too, or else you would need to convert your version to the standard generic Either all the time.
