Could it be you meant

    for x; y in [(1,2), (3,4)]; [5, 6]:

? That's the version you used in your questionnaire.

This may habe been proposed before, but how about || as in

   for x, y in sequence1 || sequence2:
	pass

sequence1 || sequence2 would be equivalent to zip(sequence1, sequence2).

I think || conveys the notion of parallel iteration nicely. The main
disadvantage is that Python newbies coming from e.g. C or Perl will
confuse it with the logical or operator at first.

The zip() builtin has the advantage that you can influence its behavior
with extra keyword arguments like pad.
