Fellow Monks,

How does one go to extend a base class that's implemented by means of a closure?

I have a base class in which the constructor initializes three fields

the base class

# constructor
sub new {
    my $class = shift;
    my $self  = {
        NAME           => undef,
        ADDRESS        => undef,
        PHONE          => undef,
    };
    my $closure = sub {
        my $field = shift;
        if (@_) { $self->{$field} = shift; }
        return $self->{$field};
    };
    bless( $closure, $class );
    return $closure;
}

I'd like to extend this class and add two more fields:

the extended class

# constructor
sub new {
    my $class = shift;
    my $self  = {
        CELLULAR => undef,
        EMAIL    => undef,
    };
    my $closure = sub {
        my $field = shift;
        if (@_) { $self->{$field} = shift; }
        return $self->{$field};
    };
    bless( $closure, $class );
    return $closure;
}

How do I make the extended class call the constructor of the base class and make sure that the two new fields are added at the same time?

I searched but couldn't find any documentation about this, not on perl monks, not on google :(
