The OP's code modified arglist by .pop(0) so I maintained the same
behavior.  This is useful if additional arguments beyond the N named
ones are used for some other purpose and you don't want to figure out
how many were taken. Otherwise, if one wants to keep arglist, Dave's
zip() solution is a cleaner way to go.
