	// Q: "why does print_to_stream() exist? why not just use ostream::write(), ostream::put() etc?"
	// A: - I'm supporting C++20's char8_t as well; wrapping streams allows switching string modes transparently.
	//    - I'm using <charconv> to format numerics. Faster and locale-independent.
	//    - I can (potentially) avoid forcing users to drag in <sstream> and <iomanip>.
	//    - Strings in C++. Honestly.
