There's a bit more to it. My pseudocode produces an extreme outlier
result, which the user really ought to pick up. It does NOT produce an
error message that stops the program. Of course it can be extended to
produce a *warning*. Stopping the program for a recoverable error is,
IMHO, really rather stupid.

The good news is that nothing is compulsory.
The bad news is that everything is prohibited.
