Correct. There's 400 `throw new InvalidArgumentException('...', 123456798)`
calls across the code base, each with a unique code number timestamp.
I didn't care for this approach either when I worked at TYPO3. :-) My point
being that I've rarely if ever seen $code used in a constructive and useful
fashion.

In my experience, worse. But that's another topic.
