Shouldn't this work just as well? numExpr = choice [ try $ float >>= return . Num , integer >>= return . Int ] It works on "Foo(10.345)" but not on "Bar(10, 103.34)". On Apr 5, 2007, at 4:09 PM, Stefan O'Rear wrote:

It seems silly that there is no signed version of natOrFloat predefined, any Parsec experts?
