Consider "my Dog $spot". From the Perl6-to-English Dictionary: Dog: a dog. $spot: the dog that is named Spot. ^Dog: the concept of a dog.
Am I understanding things correctly? If so, here's what I'd expect: a dog can bark, or Spot can bark; but the concept of a dog cannot bark: can Dog "bark"; # answer: yes can $spot "bark"; # answer: yes can ^Dog "bark"; # answer: no -- Jonathan "Dataweaver" Lang
