#125: Missin MonadException instance for lazy StateT

 Version:          |    Keywords:     
-------------------+--------------------------------------------------------
 {{{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)
