Hello all,
While using the very nice "option" combinator of Parsec recently, it seemed to me that it would be useful to have a more specific kind of combinator for optional tokens that wraps the token into a Maybe type. So, that gives: pmaybe :: GenParser tok st a -> GenParser tok st (Maybe a) pmaybe p = option Nothing (p >>= return . Just) I've been using it happily with some code of mine. Do people think that it would be generally useful to have in Parsec?
