on #2:

using @_ might be faster, but you'll probably find that it's much easier to keep your paramater order in line by using shift. It also allows you to set up defaults, and avoid warnings about using undefined parameters. Consider

$x = shift || 4;
$p = shift || 'happy';
$q = shift || return 0;

Using @_ , you'll probably end up by checking if it is defined - which is a bit more messy looking IMHO
