In section 8.3.4 of Advanced Perl Programming, "Composition" is recommended as a Good Thing (tm), but with no examples of how one might go about implementing a object made of components....
I'm not terribly interested in using the ObjectTemplate.pm -- or maybe I _am_ terribly interested, and that's the problem. In any case, can any monk show me how to re-code this object using composition methods? 
package Monk;
sub new {
   my ($name, $password, $realname) = @_;
    my %monk = (
        "name"          => $name,
        "password"      => $password,
        "realname"      => $realname,
        "level"         => 0
    );
    return \%monk;
}
sub promote {
    my $r_monk = shift;
    $r_monk->{level}++;
}
