This becomes especially useful when there exists and you need to access several things at a given level. 

my $port = $self->{center}{floor}{room}{bay}{rack}{unit}{port};
unless ( --$port->{timecount} ) {
    unless ( $port->{transmitted}
        or   $port->{received} ) {
            close( $port->{handle} );
    } else {
        $port->{timecount} = $port->{timeout};
        $port->{transmitted}
        = $port->{recieved} = 0;
    }
}

This neatly emulates the Pascal-style with ... statement.

I guess you could even use my $with_port = ... but that would be altogether to cute (and extra to type:^).

Cor! Like yer ring! ... HALO dammit! ... 'Ave it yer way! Hal-lo, Mister la-de-da. ... Like yer ring!
