Right but that only makes sense once we kill the AST before serialization right? I mean I'm happy to wrap these in `copyString` now if we know for sure that we're doing that in a later patch. But it feels beyond the scope of this particular patch. Especially that we'd also need to go through the previous code to copy the names of global records, enums, etc. anyway.

I feel like that the change to surface `APISet` and punt serialization should be separated out from the macro change. And we can wrap all the name strings in that patch so that it's a meaningful atomic commit.

Same as above.

+    Kind["identifier"] = AddLangPrefix("ivar");
+    Kind["displayName"] = "Instance Variable";

Right, naming completely new things here so worth the discussion.
To keep in line with the current convention, I don't see instance methods having an `instance.` prefix. It's just `method` as opposed to `type.method`.
Also global variable is just `var`, if we really need to add the `instance.` prefix (which I still don't think makes much sense for the above reason), wouldn't it be `instance.var`?
