Yea, but I *significantly* prefer the rules I describe. =]

The latter case is the one that is hard to write rules around. Sometimes,
you are notionally getting a reference or a pointer, and the mutability is
irrelevant. Other times, the reference or pointer present should not be
exposed through a getter.
