List comprehension...

That would be ambiguous, because it could be parsed as

   [(i, s) for i in (nums and s in strs)]

It *might* be feasible to use

   [(i, s) for i in nums and for s in strs]

If I get a spare moment or two one day I'll try this
and see whether the parser chokes. (Python's parser
is a bit strange - it's hard to predict what it can
handle and what it can't.)
