Ok, I now have a "need" for auto_ptr_new as described by the above.
Specifically I have

std::pair<boost::any, boost::any>

and in this particular case I have a pair of shared_ptr<string>'s, as a
member of my class. And as I was trying to write the constructor, I realized
that

my_any_pair(shared_ptr<string>(auto_ptr<string>(new string("text") ),
auto_ptr<string>(new string("text2") );

where I don't really want to have default construction, and then do the
assignment the "safe" way.

So the issue brought up by gotw/056 isn't as weird a case as I had first
imagined, or am I being overly cautious here?

PS
 "need" as in I'm shooting for exception safe code, but I realize that the
project as a whole has a long way to go.  I also may have made a bad design
choice a week ago and this "need" may go away. But for now, an auto_ptr_new
would be just the ticket.
