New ticket 1274 -- Add a MonadState instance for the Parsec monad

[Maxime Henrion]

	Hello all,


I just submitted a ticket (#1274) to add a MonadState instance for the
GenParser monad of Parsec.  As said in the ticket, the only drawback I
see to this is the added dependency on mtl.  I don't believe this is a
real issue though.  Of course, comments are welcome.

Cheers,
Maxime
