Testing object iteration behavior.


1. Testing that deleting properties during iteration is safe.

-- Expect stdout --
a
w
z
-- End --

-- Testcase --
{%
	o1 = { a: 1, b: 2, c: 3 };

	for (k in o1) {
		delete o1.a;
		delete o1.b;
		delete o1.c;
		print(k, "\n");
	}

	o2 = { w: 1, x: 2, y: 3, z: 4 };

	for (k in o2) {
		delete o2.x;
		delete o2.y;
		print(k, "\n");
	}
%}
-- End --


2. Test that reordering object properties during iteration is safe.

-- Expect stdout --
c
b
c
-- End --

-- Testcase --
{%
	o = { c: 1, b: 2, a: 3 };

	for (k in o) {
		sort(o);
		print(k, "\n");
	}
%}
-- End --
