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 () {...}
}
