#become: apparently (effectively) swaps object ids.
Is there anything like x oneWayBecome: y that would pass this test:
testOneWayBecome: x to: y | a b | a := x. b := y. x oneWayBecome: y. self assert: [x == y]. self assert: [a == y]. self assert: [b == y].
(Not related to my earlier collection empty question)
