	// Two things to know about NSSet:
	//
	// - NSSet assumes its elements will never mutate. It breaks if they do.
	// - Unlike NSDictionary, NSSet does not copy its unique objects. It stores
	// the original pointers.
	//
	// Bottom line: DO NOT MUTATE OBJECTS THAT ARE ELEMENTS OF AN NSSET. The
	// code below demonstrates the kind of bugs you could run into if you
