Immutable objects are simple. They can only be in one state, which is carefully controlled by the constructor. One of the most difficult elements of program design is reasoning about the possible states of complex objects. Reasoning about the state of immutable objects, on the other hand, is trivial. Immutable objects are also safer. Passing a mutable object to untrusted code, or otherwise publishing it where untrusted code could find it, is dangerous — the untrusted code might modify its state, or, worse, retain a reference to it and modify its state later from another thread. On the other hand, immutable objects cannot be subverted in this manner by malicious or buggy code, so they are safe to share and publish freely without the need to make defensive copies. ↗

It may interest you to know that my breakup with Terry and this mystery did not happen concurrently in real life. That is a writer's device, which places Gabriel under even greater pressure when the mystery begins to reveal itself. ↗

In a recent decision of the Supreme Court, not made, however, by the full court, and concurred in by only four justices, it was held that the seller of a patented mimeograph could bind the purchaser to use only his ink in the machine, though the ink was not patented. ↗
