But I feel moved to speak.

I honestly feel that auto_ptr is a pioneer. The mother of smart
pointers if you will. I have great admiration for the work that Greg
and Bill Gibbons did on auto_ptr, and under tremendous pressure I'm
sure. I know that there were smart pointers before auto_ptr. But
auto_ptr managed to satisfy the entire standards committee in 1997. And
as I have gradually come to believe just over the past year, I think
auto_ptr is the forerunner of generalized move semantics. There is
great parallel between auto_ptr_ref and John's move_t I spoke of
earlier. Greg and Bill were designing working move semantics in '97 and
I'm still struggling with this issue 5 years later.

My hat is off to Greg and Bill. A job well done! I can not imagine
trying to design move semantics today without auto_ptr to stand on.
