[Haskell-beginners] Small question

Hi there, I have created a function mkc: mkc :: (a -> b) -> a -> m b mkc f = (\x -> return $ f x) which works wonderful in statements like: number <- many1 digit >>= mkc(read) But somehow I think this function should already exist, it is some kind of lifting. If it exist where can I find it? Or is there a reason, why it isn't in prelude, because it is more elegant way to solve this problem. Thanks in advance, Edgar
