Back to the original question from 2 mails ago:
How else would we be able to use the same function in copy_to and
copy_from variants?

Back to my other question:
Do you have any real life examples where you can trigger such bugs or is
this only "potential"?
IOW, what I *think* you're trying to do sounds to me like unnecessary
complication with no apparent gain *at* *all*. So show me why you want
to do it: code it up, trigger a bug and show me why your version is
better. No "but but it might be a good idea", no "potentially maybe",
none of that maybe stuff. Write it, send it with instructions how
someone else can apply it and trigger the issue. Ok?
