I would assume that this is a FAQ, but it seems to be impossible to get reasonable search results for overloaded terms like "perl product" or "multiply array."

At any rate, I have this procedure for multiplying a list of numbers:

sub product {
    my $list = shift;

    my $prod = 1;

    foreach my $num (@$list) {
        $prod *= $num;
    }

    return $prod;
}

However, with the loop and all, it seems like a terribly inefficient method of doing such a thing. Anyone have a smarter way?
