No. It's a very different thing handled by a special rule in C++.
This isn't helping. You keep saying its different but not how.
In one case a reference is returned, in the other an rvalue is returned.
This is a trimmed down example:
int &foo(int &val) { return val; }
What I read from you (and I could be wrong) is you are saying this is not
valid:
foo(foo(foo(1)));
Is that right?
Yes. My point was to illustrate that a special rule that works in a
situation can't help another.
Another situation that's already solved? Don't see the point.
No. That situation leads to undefined behavior.
In D that situation is invalid. You can't have ref members.
