Rvalues masquerading as references to constant values have caused 
enormous harm to C++, culminating in the "fix" that was rvalue references.

Let's not repeat that values. Rvalues are rvalues and should stay that way.

What is in essence the problem to be solved? My understanding is that a 
thunk function would be appropriate here.
