My question is: do you _really_ need rvalues to bind to const ref for performance? If not, what _do_ you need it for? Is it an instinctive reaction against passing structs by value from C++98 days?
imho it's the compiler job to pass by value or ref. For a function that is inlined it should be able to make its on choice.
