Dec 3, 2011 at 9:48	comment	added	Dave Clarke		This is another option. And then you have subtype relation boolean < short < integer < long. Where + is addition-modulo-overflow. That's fairly natural, programmatically.
Dec 3, 2011 at 8:55	comment	added	Peter Taylor		Surely there's a third option of making + be XOR, which is the most natural one by analogy with larger integer types. (Of course, in twos complement by the standard convention your two Boolean values are 0 and -1, but that's largely irrelevant).
