[Haskell-beginners] Common Method for [Maybe a] -> [a]

[Leonhard Applis]

Hey there,

I've got a method:

demaybefy  :: [Maybe  a] -> [a]
demaybefy []  =  []
demaybefy (x:xs) =  case x of
Just x -> x : demaybefy xs
Nothing  -> demaybefy xs


However, i feel that there is a method from preload/list/maybe that does exactly the same, but i cannot find it.
Can someone help me?

best regards
Leonhard
