Absolutely. Keep in mind that the OP is coming from a Ruby background and TFA targets people more familiar with high-level interpreted languages than with C/C++.
BTW, I think though I cannot be sure that both the GCC and MSVC std::string implementations use this optimization in release mode, but I gotta dash and don't have time to verify this fact, so take it with a grain of salt, if you will.
