Hello all, I have just created a new ticket (#1222) to suggest the addition of a new parser combinator for Parsec, called "optionMaybe". It is just specialized version of the existing 'option' combinator: it wraps the result into a Maybe type with the expected semantics. As noted in the ticket, it has received positive feedback on the haskell-cafe mailing list and on the #haskell IRC channel. Cheers, Maxime
