I wouldn't want to encourage partial functions without even an error
message. Usually with Either you'll want to use the unexpected value in
the error msg, e.g 'either (error . ("xyz: "++) . show) id'.

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?
