That reads awkwardly, I find. This is how I'd write it:

sub getRef {
    my $self = shift;

    $_ = $self->getNodeById( $_ )
        for grep { $_ and not ref } @_;

    return ref $_[0];
}

It maps more closely to the way I think of the problem. You can almost read it out in natural language: "filter it through $self->getNodeById() for every element that is true and not a reference".

Makeshifts last the longest.
