You could also just have one method that is both a getter and setter
sub level {
my $self = shift;
if ( @_ ) { $self->{ Level } = shift;
return $self->{ Level };
}
What we are doing is checking if any other arguments are passed,
apart from the reference to the object it's self, if there are we just
grab the next one.
