in reply to Eliminating "used only once" warnings from List::Util::reduce

This is the type of bug that makes Perl enormously interesting for me. Here's my last attempt: 
 
#!/usr/bin/perl -l

use strict;
use warnings;
use List::Util qw/reduce/;

our($a, $b) = @_;
my $reduce = reduce { $a + $b; } 1, 2, 3, 4;
print $reduce;

    Slick, however the point of the question was missed. If I wanted to solve it in "user code", there are at least a half dozen ways to do it. The question is dealing with how to solve it in either the module's code or perl code.
