Yeah.

But I do know something about it, and I have already expressed my
informed opinion.  Having you come along to say that you don't know
anything about it at all, but that you nevertheless think I am
mistaken, is bizarre.

Perhaps you could study the code in regexec.c for a little bit of
time, say fifteen minutes, and then make this suggestion again in
light of what you discover.

I have no problem with discussing this in more detail, but I don't
think it would be a good use of my time to discuss it with you when
you haven't looked at the code.
