	// A value of type [u]int8_t is treated as a character when being put to an
	// output stream, which can result in invisible characters being printed. To
	// avoid that, such a value needs to be casted to a wider type. It can be done
	// by using the following template to find a target type to cast our value to.

	// tedious typename stuff.
