I look forward to finding out the new name for MaybeT then. ;)
That's a bit unfair, because the Maybe data type has a clear meaning which also holds for its Monad instance.
That's not the case for Either. The Either data type doesn't propose a special meaning to the 'Left' or 'Right' case, but the Monad instance of Either does.
Isn't just having a discussion about such a contradiction at the end the reason why Haskell is the language it is?
I also think that Maybe so far is consistently used for exception handling without exception information. Thus I am fine with MaybeT.
