A better mod (%) operator?

I almost have a working example with **overload**, but
i can't get it to work - wantarray is being fussy with me.
The problem with overload though, is that you cannot define
some new token such as /% - you have to use an existing
one. This should get you started, but like i said, it
doesn't work. I have provided a subroutine at the bottom
that does work, i would appreciate it if someone could
tell me what i did wrong. I chose * as the overloaded
operator just to show that the overload sub is being
called, i originally used %

`package mod;
use strict;
use overload '*' => sub {
my $div = int(${$_[0]} / ${$_[1]});
my $mod = ${$_[0]} % ${$_[1]};
return wantarray ? ($div,$mod) : $mod;
};
sub new {
my ($class,$val) = @_;
return bless \$val, $class;
}
package main;
use strict;
my $i = mod->new(90);
my $j = mod->new(60);
my @x = $i * $j;
my $x = $i * $j;
print "@x\n";
print "$x\n";
my @y = mod(90,60);
my $y = mod(90,60);
print "@y\n";
print "$y\n";
sub mod {
my $div = int($_[0] / $_[1]);
my $mod = $_[0] % $_[1];
return wantarray ? ($div,$mod) : $mod;
};
__END__
yields:
30 <-- this should be 1 30
30
1 30
30
