[Python-ideas] How assignment should work with generators?

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' 
England, e.g.:

     x, y, . = iterable

Not sure about the second comma though.
