Thanks. With this input, I've found that including a CodeRef wrapper isn't
necessary. This code appears to work as desired:
my $parser = XML::Twig->new(
twig_roots => {
'title' => sub { $self->title_handler(@_) },
'description' => sub { $self->description_handler(@_) },
'item' => sub { $self->item_handler(@_) },
},
);
