I think the advantage in perl6 is that you can create *new* operators. That means the modules don't have to overload already used operators. For instance I've played with building a units module that overloads 'ft' and 'in' as postscript operators. But if you see my $distance = 5ft + 6in; You know that something new has happened here since those arn't standard operators. ;) Just my two cents.
