I've read DIP69 and there were a few lines about scope ref. But I'm
not sure whether I understand everything correct (because there is no
concrete application example for my case): will DIP69 create the
possibility to pass rvalues and lvalues alike to a function without
the abuse of templates? Or did I got that wrong?
DIP69 is more or less dead, we're going with a variation of DIP25
(although that one still has holes).
As for rvalue ref, it would enable them safely, but it is not a part
of that DIP (or DIP69, AFAICS).
And I thought for a moment, we have a solution in sight... :)
Knee-jerk response: if no "return" attribute on a function it should be
safe to bind rvalues to ref parameters. Of course that's impractical as
a default so explicit "auto ref" would be needed. -- Andrei
