Stdlib actually includes a programmable pretty-printer[1], with two instantiations [2][3], as demonstrated below:

$ lua

	create = function: 0x109c78c5f,
	resume = function: 0x109c78caa,
	running = function: 0x109c78d33,
	status = function: 0x109c78d57,
	wrap = function: 0x109c78e3f,
	yield = function: 0x109c78e6d,
}
