Hmm, I didn't like the options below because they say to me, "consume everything:"
x, y, * = iterable
x, y, ... = iterable
Believe the question behind the idea was, how to grab a couple items and then
*stop?* If the syntax route is chosen, I'd expect something that tells me it is
going to stop, like a "full stop" as the period/dot is called in jolly ol'
x, y, . = iterable
Not sure about the second comma though.
