Ticket #125 (new defect)
Missin MonadException instance for lazy StateT
|Reported by:||guest||Owned by:|
System.Console.Haskeline.MonadException defines MonadException instances for the monad transformers in the transformers except for the lazy version of StateT.
I don't see a problem in adding an instance for both, but if it were, it should be more clearly explained in the haddocks that StateT refers to its *strict* version (right now, one needs to open the source to understand why no MonadException instance is found)
