💅 NAME 💅

std::experimental::in_place_t - std::experimental::in_place_t

okay bestie, welcome to std::experi...::in_place_t(3) from the C++ Standard Libary man pages 💖 this one is short but iconic.

✨ Synopsis ✨

Defined in header <experimental/optional>:

struct in_place_t {};

(library fundamentals TS)

So std::experimental::in_place_t is an empty class type, and its whole job is to disambiguate the overloads of constructors and member functions of that take arguments (possibly a parameter pack) for in-place construction of some value. lowkey a tiny little tag with main character energy 🎀
