Thinking about this further, it seems to me that it is in fact more
important that turning a message into a string produces the same result
no matter how many times it is called on the same (otherwise unmutated)
object than that it avoid mutating the object tree itself.  (This is
called idempotence and it is an important interface concept in certain
circumstances, and I think this is one of them).

The documentation should make the expectations clear, however.
