I think you mean it works as intended in your use case.  I am talking
about something else.

My experience says that this kind of feature is likely to fail in
various peculiar cases, which would make it a maintenance burder.
Also, it is likely to show show strange confusing behavior which would
lead to trouble in debugging.  We are better off without it.

The other approach has the virtue of being entirely internal.  It will
not require an announcement, or adding to the Lisp manual.


+1, likewise a related earlier message.
