Hi, monks of Perl!

I have a number of variables where I need the name for logging. The names are known a priori, and a nominal amount of munging needs to occur within a function.

Pseudo-code for what needs to happen is as follows:

#!/bin/env perl

use strict;
use warnings;

my ($a, $b, $c);
$a = $b = $c = 0;
foreach my $v (qw/a b c/) {
    func($v);
}

sub func {
    my $v = shift;
    print "v = $v\n";
    eval($v = $v * 2);   # incorrect syntax
}

I know the eval() statement above is wrong, but I can't get either the expression or block form working. I'm rather confused.

Any enlightenment you can pass on would be greatly appreciated!
