Unrelated to your question, but worth mentioning, is that it is a good idea to use explicit returns. A subroutine will implicitly return the value of the last expression evaluated, however this behavior can be unclear to maintenance programmers.

sub getValue {
        my $self = shift;

        return $self->{theValue};
}

You may wish to read Damian Conway's Perl Best Practices. It has a large amount of this sort of advice to offer, as well as discussion of the reasoning behind the recommendations. Some of the book's recommendations are controversial, others are widely accepted. A little searching at the monastery should provide a number of good links discussing PBP.
