Eh, true. But actually, I wanted both: Iterating over the pairs in the initializer list by reference and still using the move-ctor from there. > That use of std::move is actually a pessimization, as it prevents RVO. How so? The RVO would be to do the ::std::move(). So this is just making that (needlessly) explicit, isnt it?
