If warnings are switched on you will get an 'Use of uninitialized value ...' message once you get to the last time around the loop as print tries to access one more element than is in the array. This stops the warning.

use strict;
use warnings;

my @names = qw{rita sue bob daisy};

$, = q{ };
$\ = qq{\n};

foreach  (0 .. $#names)
{
    print
         $_ == $#names
       ? $names[$_]
       : @names[$_, $_ + 1];
}
