I'm not sure if I should fall to my knees in admiration of a Cool Hack,
or recoil in horror at a Bogus Kludge :-)

The code looks like it should return [('a', 'a'), (1, 1), ('b', 'b'), (2,
2), ('c', 'c'), (3, 3)] but of course it does not: the arguments for zip
are not independent.

I guess it is more of a Neat Trick, with a dash of Gotcha For The Unwary.
