Delegation has drawbacks compared to inheritance : you can't use a object that delegates to class Foo where an instance of Foo is expected. Unless Foo and the class that delegates to Foo both inherit from a common (abstract) superclass (ArrayInterface ? Dictionary ?) (Duh, this is just starting to sound like Java.) How do you override vtable methods from within Perl 6 ?
