in reply to XML::LibXML::NodeList get_node

get_node is implemented much like this:

sub get_node { my ($self, $pos) = @_; $self->[$pos - 1]; }

So $nodelist->get_node(0) is the same as $arrayref->[-1].

I wouldn't rely on it if I were you though. It's undocumented behaviour that is merely an accident of the internal implementation of XML::LibXML::NodeList, and could theoretically change in the future.

use Moops; class Cow :rw { has name => (default => 'Ermintrude') }; say Cow->new->name
