(Resolved) Language: Allow interface methods to have other namespaces than "public"

[lth]

In AS3 and in the RI, interface methods are always public. They can't be annotated as public, and any "use default namespace" pragma in the context is silently ignored. Implementing methods must be public.

I think that we should allow interface methods to be namespaced just like other methods. Specifically:

• The default namespace in an interface should be whatever the default for methods is in the surrounding context (ie, same rule as in a class).
• There should be no limitation on the namespaces that can annotate an interface method (including "private").
• The implementing method must use the same namespace annotation as the interface method (after resolving defaults).

Agreed. No idea why it is this way.

Waldemar notes that "private" is sterile. Otherwise, we accept this.
