I agree that's highly desirable. But it seems to point in a different
direction from the existing feature.

The feature in reset() now gives predictable behavior when doing a reset to
the same pointer twice. It doesn't prohibit it. I just wanted to point out
that Peter's revision of smart_ptr removes this feature.

Changing the existing check to an assert, simple or sophisticated, that
makes this illegal would be OK for me, but maybe not for others.
