After updating to Parsec 3.1 from 2.x, code using many1, such as word = many1 letter
fails with
No instance for (Stream s m Char) arising from a use of `letter'
I found a mailing list post claiming that adding {-#LANGUAGE NoMonomorphismRestriction #-}
to the top of the source file would solve the problem, but it did not.
