I'm not an expert in Moose, but looking at it makes me wonder why you are referencing it. I took the reference to age out of the sub.
sub show_person { my $self = shift; return $self->name(); }
If it's not required, then it wasn't necessary to return it, at least to my way of thinking. My logic could be off, which happens frequently, but here's the code that I ran. It returns "Bob" with no warnings.
package Person; use Moose; has 'name' => ( is => 'ro', isa => 'Str', required => 1); has 'age' => ( is => 'ro', isa => 'Str'); sub show_person { my $self = shift; return $self->name(); } __PACKAGE__->meta->make_immutable; no Moose; 1; my $person = Person->new(name => "Bob"); print $person->show_person(), "\n";
