I am not in position to judge their reasons --- I never had this need. Maybe
I avoided their specific problems somehow. Or these problems are not
frequent enough. Anyway, I can speak only for myself. And I am not convinced
yet. :-)

Hmm. I expected that _you_ will tell in your proposal something like that:
"There is this huge set of problems. These are specific examples majority of
programmers are struggling with frequently. (Stone cold facts and examples).
And this is how I propose to change our hard life to the better.
(Solution)." :-) Something like that. Instead you proposed solution without
proofs of problem. I guess I had wrong expectations.

In all cases? Well, programming itself is well known source of hard to find
bugs. :-) I don't think that this is valid argument in this particular case.

And still nobody uses auto_ptr like this: p.get()->XXX(). :-) If we can
simplify our life, we should. If we can save 1 character in frequently used
idiom, we should.

I have some ideas how to deal with this problem. But all of them fall
outside of discussion about smart handles.
Thanks,
