Yes, I'm aware that this is what you are thinking about now.  But I
think you diverged a bit from the question I had answered in this
subthread.  I had answered something different.

This answer was about (please go some messages up...) your question
about why we don't use to change function values (destructively) as we
once did with lambda forms before lexical binding existed.

Michael.
