Re^2: How can I keep object arguments private

[walto]

Thanks, that helped with the readmore tag.

The other problem seems to be more a problem of the object design. With

$self->{'countries'}->{$country_code}->{'fullname'}= $country;
$self->{'countries'}->{$country_code}->{'warnings'} = \%warn;
return $self->{'countries'};

I am able to return just the wanted values without deleting any other properties of the object.
Are there any other ways to return just the wanted value?

Invoke laziness first: is there any reason I need to delete the other properties? Or will providing a wanted_value method (obviously a better name is needed!) suffice?
