Fascinating, I was sure that is was a handy way to indicate that one ignore a results in structured-binding (like it is the case in python). But reading at the C++ standard to answer you, it turns out "_" is a legal variable name in C++, so this has no special meaning an you could just use "_" in " _ + _".
Well, thanks for asking, I will just use "componentType = xxx.second" then.
