+1 from me. I often use such functions when working in GHCi, and it is consistent with the existence of fromJust. That said, I understand the opposition, and these functions should never be used in production code. Maybe we should put the lot of them (together with head, tail, fromJust) into a "Partial" module?

When working with Either, I am often missing two simple functions: fromRight :: Either a b -> b fromLeft :: Either a b -> a
It has been implemented a couple of times: http://hayoo.fh-wedel.de/?query=fromRight
But I don't want to depend on yet another library for such a basic function.
Could it be added?
