1) I will move the my declaration.
2) Yes @foo is shorter. My code should have read... 
#!/usr/bin/perl
use warnings;
use strict;
my @foo = ( 1 , 3 , 5 , 7 );
my @bar = (0, 2 , 4 , 6 , 8 );
print STDOUT my @foobar = map { $_, shift @foo } @bar;

I'm assuming that this is my problem, no? I do get the proper result "012345678"...just with a warning.
3) I guess I have a talent for ugly... and warnings :-(
