I think there should be a different function for this,
rather than overloading it onto iter() by type-testing
the second argument, which is rather un-Pythonic.

BTW, I never knew iter() had a second argument. Having
just looked up what it means, I think it was a mistake
to put even the existing two functionalities into one]
function -- especially given the comment in the docs
about it doing "very different things depending on the
presence of the second argument"!
