Re: Proposal: add fromRight and fromLeft to Data.Either

I wouldn't mind something like this being available... but only if prefixed with the word "unsafe" or "partial" or other such scary words. -- Dan Burton On Fri, May 20, 2016 at 1:34 PM, David Feuer wrote:

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?
