> Most excellent! Thanks.
I frequently use Hoogle[1] when I need a function, that I think must
exist, but do not know how it is named. Try:

(a -> Bool) -> [a] -> ([a], [a])

With the recipe from [2] you may even invoke hoogle from within ghci:

ghci> :hoogle (a -> Bool) -> [a] -> ([a], [a])

Hope that helps.
