I don't know why you're getting the warning; I don't with this script:

#!/usr/bin/perl -w
use strict;
my @foo = ( 1 , 3 , 5 , 7 );
my @bar = ( 2 , 4 , 6 , 8 );
print STDOUT my @foobar = map { $_, shift @foo } @bar;

Unless, that is, you left the @baz line in. Note that you are destroying @foo in the process (by calling shift); if you do it more than once, you'll have an empty array the second time.
