It's a flaw in MonadPlus, since it allows two different behaviours and really should be two different classes. See http://haskell.org/haskellwiki/MonadPlus.
Ah, excellent. So it sounds like at least in Haskell prime, I'll probably be able to use MonadPlus to do what I want, because MaybeT and ErrorT will be instances of MonadOr instead. Mike
