By the way, ever since we came up with "attr" in Zurich, I've been hating it more and more. I'm thinking that "has" reads a lot better: class Dog is Mammal { has Nose $.snout; has Ear @.ears is cut("long"); has Leg @.legs; has Tail $.tail is cut("short"); method Wag () {...} } Or, along the lines of "my" lists: class Dog is Mammal { has ( Nose $.snout, Ear @.ears is cut("long"), Leg @.legs, Tail $.tail is cut("short"), ); method Wag () {...} } Larry
