Say, what's the deal with transforming every element of @_ after the first but then returning the second element? You never get constant values as parameters?

Anyhow, if you write code as list-processing stuff with nice indentation you get something that even looks Pythony. What could be prettier than that?

sub getRef {
    shift;

    # !!! $this is a global
    return
        map ref $this->getNodeById( $_ ),
            grep $_ && not ref,
                @_;
}
