As a person involved in this space, if there's ever an RFC for full-on f-strings there's a good chance that I'd be the one who writes it, and I can tell you for certain that I would not make `f"foo"` incur an allocation; it would return a std::fmt::Arguments rather than a String.

just for clarity's sake: you mean an RFC for rust and not c++ right?
