Potentially buggy test

[fabiospampinato]

The following test looks buggy to me:

sinuous/packages/sinuous/observable/test/child.js

Lines 230 to 269 in ece2c65

	test('insures that new dependencies are updated before dependee', function(t) {
	var order = '';
	var a = o(0);
	var b = S(function x() {
	order += 'b';
	console.log('B');
	return a() + 1;
	});
	var c = S(function y() {
	order += 'c';
	console.log('C');
	return b() || d();
	});
	function z() {
	order += 'd';
	console.log('D');
	return a() + 10;
	}
	var d = S(z);
	t.equal(order, 'bcd', '1st bcd test');
	order = '';
	a(-1);
	t.equal(b(), 0, 'b equals 0');
	t.equal(order, 'bcd', '2nd bcd test');
	t.equal(d(), 9, 'd equals 9');
	t.equal(c(), 9, 'c equals d(9)');
	order = '';
	a(0);
	t.equal(order, 'bc', '3rd bcd test');
	t.equal(c(), 1);
	t.end();
	});

At line 264 we are basically just updating the observable from -1 to 0. The D computed depends only on this observable and returns observable+10. Then at line 266 we say the D computed shouldn't have run, why shouldn't it?
