	42	### Demo game
	43
42	44	Finish the little demo "game" where you can move a block around the screen with
43	45	the joystick (i.e. bring it up to par with the original demo game that was written
44	46	for SixtyPical)
45	47
46		### Operations on 16 bit values
	48	### Self-reference in signatures
47	49
48		Compare word (constant or memory location) with memory location or pointer. (Maybe?)
	50	A vector might store [the address of] a routine which changes the vector. Thus its
	51	signature might look like `vector foo outputs foo`. Thus we need to support that.

	74	* Compare word (constant or memory location) with memory location or pointer. (Maybe?)
71	75	* `copy x, [ptr] + y`
72	76	* Maybe even `copy [ptra] + y, [ptrb] + y`, which can be compiled to indirect LDA then indirect STA!
73	77	* Check that the buffer being read or written to through pointer, appears in approporiate inputs or outputs set.

25	25	There are also two type constructors:
26	26
27		* X table (256 entries, each holding a value of type X, where X is `byte`)
	27	* T table (256 entries, each holding a value of type T, where T is either
	28	`byte` or `word`)
28	29	* buffer[N] (N entries; each entry is a byte; N is a power of 2, ≤ 64K)
