The fact that immutability can be circumvented by technical means is
in my opinion inconsequential.  Marking an object instance immutable
conveys intent. You can build additional logic on top of the
immutability hypothesis. If someone intentionally circumvents
immutability, the ensuing problems are theirs, not ours.
