Improve restrictions on attributes/operations when maplike/setlike are used

I don't quite understand 1)?

Consider this IDL:

interface Foo {
  static boolean has();
  setlike<long>;
};

Per current spec this would be disallowed. The proposal is that it be allowed. The setlike declaration will create a method called has on Foo.prototype, and the static thing will create a method called has on Foo, but there's no conflict there, so no reason to forbid this IDL.

Got it! SGTM.
