Under Moose you need to add traits => ["Array"] to the attribute declaration. See Moose::Meta::Attribute::Native::Trait::Array.

With Moo you'd use handles_via => "Array" but you'd need to install MooX::HandlesVia first.

package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name
