You're not a fan of e.g. catMaybes xs = [x | Just x <- xs] or the do-notation form: catMaybes xs = do Just x <- xs return x then? (I actually prefer foldr (maybe id (:)) [] but that's probably just me :) _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
