Ross, thanks a lot for adding MaybeT!
Unfortunately I have just another wish. In a parser I like to show by
types whether the parser can fail or not. To this end I have a type
parameter for a monad transformer that can be instantiated either by
MaybeT or by IdentityT. The only problem is, that there is no IdentityT in
transformers package, yet.
