I'd agree with that if I agreed with what you later say about bindings.

Ah! "Target" is a good word.

Oh, yes, they are bindings. Thinking about this a bit further, a
binding is anything that increases the refcount of an object. If you
don't want to use the word "binding" to describe this, come up with some
other word that describes the same thing.

Right. And if I agree with MvL that computed bindings are names, then
this is fine.
Guido? Are you paying any attention to this discussion?
