really, these functions should be passed by && and using std::forward on assignment. however, this means writing a lot of extra code for every single class, as well as explicitly calling move in a lot of cases. In the case of std::string, passing by value and calling std::move is the correct approach, especially if the string is created as an rvalue, then it is only created once and moved into the dest. Whereas with a const ref, the string is created and then copied into the dst, basically creating 2 copies. The same thing happens std::function, and well any object. However, accepting everything by value sucks if you call a constructor from within a constructor, as now you need to create 2 impls that accept by value and the other by rvalue. All of this extra code to have a more efficent impl just isn't worth it when, going by the benchmarks, makes no measurable difference (i count anything within >= 1ms as measurable).
