That's too bad.  Especially for someone who participated actively
in that thread and proposed (it seemed) a solution for it, to
which Stefan seemed to give the go-ahead.  Sorry you feel that way.

I'm glad that my participation reminded you of #8368, and you then
brought it into this discussion.  You were right to do so.  It is
relevant - not just the bug but the discussion thread.

And just what problem is that?  You say there is a problem to
fix in my code.  What is the problem?  (And what is the fix you
have in mind?)

Why should that be replaced?  And if it should, just what should
it to be replaced with?  That is part of deprecating something:
tell users what they should change to what in existing code. E.g.,

(old-foo this that) ==>
  (new-bar something-else that 42 (1- this))

or whatever.

Suggest all you want, if it makes you feel better.  But I do not
feel that I interfered in any way.  Nor do I think I have anything
to apologize for.  But you are welcome to apologize to me for
suggesting that I have done something wrong and have something to
apologize for. ;-)

There might be some incomplete or incoherent changes that still
need fixing or finishing.  Dunno.  But if so, none of those are
my doing.  And in spite of that state, no, I would not think of
asking you or anyone else for an apology for that.  People do
their best, whether or not what they do is TRT or sufficient.

On the contrary - to the extent that things will be improved,
bravo and thank you, to you, Leo, or whomever.  To the extent
that that is not so, or only partly so, I hope that the job
can be finished as mentioned in bug #8368.

It is neither fate nor accident, but the result of someone's
doing.  See above, about people doing their best whether or
not it is sufficient.  Yes, that is part of life.
