yes!

yes, keywords or something else would be necessary.

I'm not sure...

I've just responded to Andrew's earlier email...

I wonder if some of this is confusion over the semantics of "private" ?
 - Java-style Private being class-wide lexical bindings
 - Ruby-style private meaning private to the object, dynamically dispatched, by only accessible via self calls.

then (for the Ruby design) there is the question of whether the self calls
 - may or must have an explicit self receiver
 - may or must have an implicit self receiver 
 - whether the explicit/implicit distinction changes the underlying semantics
