Well, it doesn't preserve the identity of the collection. There's nothing
that says I have to care about what the method returns.

	aCollection := (1 to: 10) asSet..
	...
	someCondition
		ifTrue: [
			aCollection
				removeAll: aCollection;
				add: someElement.
			^true]

#removeAll *has* to be destructive to the receiver object. As well, it is
supposed to return the objects removed, not the new state of the recevier.

Later,
