filter

Let's say I have a list, and a filtering function. Using something like

>>> filter(lambda x: x > 10, [1,4,12,7,42])
[12, 42]

I can get the elements matching the criterion. Is there a function I could use that would output two lists, one of elements matching, one of the remaining elements? I could call the filter() function twice, but that's kinda ugly :)

Edit: the order of elements should be conserved, and I may have identical elements multiple times.
