+1 from my side, obviously.

😯 ... ok - I misunderstood that part.  No, the examples in the manual
are fine.  It's only that I never expected these semantics (so didn't
search for any examples 🙁).

Probably because it is so unexpected that something named "...-default"
is let-bound around a call to modify it's behavior.  But the semantics
make sense.

So I don't know, my impression is that having the word "default" in
the name of the variable is not good.  Not because it would be
inappropriate, but because of how most other variables with "default" in
their name are typically used.  I think a different term ("base",
"fallback", ...?) could be better.

BTW, what I did not yet understand is why you must locally modify the
behavior of `occur' in this case, but not for other `occur' invocations.


Thanks,

Michael.
