OK, thanks.

There's one thing I cannot seem to be able to find in the
documentation you added: how can a Lisp program know that it is being
run under a "labeled narrowing", and in particular what is the label?
Without knowing that, how can Lisp programs adapt their behavior to
this special kind of narrowing, or even just break out of it using
without-narrowing?
