The function itertools.combinations might benefit from making the 'r' (length of the combinations) argument optionally a sequence. With that change one could call combinations(sequence, [2, 3]) in order to get all combinations of length 2 and 3. In particular, one could call combinations(sequence, range(len(sequence)) in order to get all combinations of given sequence. The change would be backwards compatible as it would check for sequential arguments.

The function itertools.combinations might benefit from making
the 'r' (length of the combinations) argument optionally a sequence.

With that change one could call combinations(sequence, [2, 3]) in
order to get all combinations of length 2 and 3.
In particular, one could call combinations(sequence,
range(len(sequence)) in order to get *all* combinations of given
sequence.

The change would be backwards compatible as it would check for
sequential arguments.
