Does it?

    role Foo {
        method bar() { "x" }
    }
    role Bar {
        method bar() { "y" }
    }

    class Baz {
        does Foo;
        does Bar;  # does this count as double declaration?
    }

I'd say we're going more toward the conflict side of things.  That is,
I'd expect:

    sub foo() { 1 }
    sub foo() { 2 }

To be an error.  However, I'd expect:

    sub foo() { 1 }
    &foo ::= sub () { 2 };

Not to be.
