A problem with this is that it doesn't generalise smoothly
to products of more than two sets.

A mathematician would think of A x B x C as a set of 3-tuples,
but in Python, A * B * C implemented the straightforward way
would give you a set of 2-tuples, one element of which is
another 2-tuple.

Keeping it as a function allows products of arbitrarily many
sets to be expressed naturally.
