I wonder if it would be best for it to be a keyword-only argument. So
many of the utility functions on iterables are foo(*iterables) that I
might be inclined to think enumerate(foo, bar) is equivalent to
enumerate(chain(foo, bar)), but enumerate(foo, start=bar) is pretty
obvious. And if you consider that the enumeration is prepended to the
values of foo, enumerate(foo, bar) is "backwards." Just saying..
