I believe so. It's reliable as long as 'string' was already a token,
but not otherwise. It doesn't give a random value, at least, it just
fails to update it. (So d[string] would return whatever value it had
before the d[string] = whatever line).

I wondered this too. I think it was Mark coding for all possible

I didn't notice this, but your logic makes sense to me.
