Is there a function like Either#merge in Scala - an extension on Either<A, A> that returns A ? Shall I PR one?

I believe we had this at some point or was discussed with @Yeray Cabello but can't find it now so I'd say go for it 😊, thanks!

We went for collapse as the name back then. Since the terminology used in fold used that expression: Collapsing to a single type.

In the end, it's either.fold(:: identity, :: identity)

Something happened and I never PRed it.

It's your cat, though, skin it any way you see fit.
