Almost completely useless. Multiplying an *iterable* by an integer
will often be useful (eg multiplying list by int), but multiplying an
*iterator* (or even just adding one to itself) is going to be useless,
because the first time through it will exhaust it, and any
well-behaved iterator will remain exhausted once it's ever raised
StopIteration. (Note that the 'class iter' that I posted earlier is
NOT well-behaved. You can add something onto an exhausted iterator and
rejuvenate it. It'd take a couple extra lines of code to fix that.)
