That's an interesting point the tip makes. Is there guidance on how to use the emplace_back() added to c++17 which returns a reference to the constructed element? The reference returning emplace_back() is used frequently in the code to construct a new element of a struct and then fill in its members, as opposed to creating a new struct then push_back() to copy the memory in.
