Can anyone explain to me why this test passes? I have read through the Types page on the dlang website and can't find anything that would explain this. Is it a bug or am I doing it wrong?

	uint x = 0;
	(x += 1) %= 2;
	assert (x == 1);
	ubyte y = 0;
	(y += 1) %= 2;
	assert (y != 1);
	// though I expected y == 1

Here's a table of all the types I tried ++x %= 2, where x has type long (L), int (I), etc:
	L	I	S	B	uL	uI	uS	uB
	1	1	0	0	1	1	0	0
	0	0	0	0	0	0	0	0
	1	1	0	0	1	1	0	0
	0	0	0	0	0	0	0	0

It all seems very odd.

Dunno why I didn't try it earlier, but splitting it across lines like

y += 1;
y %= 2;
assert (y == 1);

works. So, bug, then?
