I do not get your point.  Errors are a horrible problem we face in every
part of all the code we run.  Software that catches errors is a necessity,
but it does not work perfectly.  I get blown away many times a day and have
to reboot my Chromebook. I cannot easily list all of the things I am
constantly watching out for:  network service disconnection, spilling my
drink on my keyboard, power failures ..., relatives dying, doctors
appointments, ...

I regard errors from declarations as wonderful reports that usually show up
during SBCL compilation.

Anything I seem to state should be taken as a question.  I am at least 77
and feeble.
