[In a somewhat unrelated question... I saw some code the other day that used Either as if it were a monad. And yet, I don't see an instance given in the standard libraries - even though there should be one. I can see Functor (Either a), but not Monad (Either a) or even Monad (Either String)...]
It's used in the Error Monad. -- Rich JID: rich@neswold.homeunix.net LOI: https://www.google.com/reader/shared/00900594587109808626
