I considered $ for $top, but I was sure you would not want to waste $ in 
this. In my original suggestion, I also suggested None as in
a, b, c, None = source
as another possibly to signal

"I want source iteration to stop even if there are more items, and I 
don't want an exception raised even if there are, because I think I know 
what I am doing and I do not want it to be considered a bug."

Any other short spelling/signal would be fine, too.
