Yes. It's more efficient. The ref-counted concept still exists, so
this is a smarter design. It's in line with current C++ design
(iostreams), it's efficient, and it's flexible when used with other

Either a usage pattern that's not possible with the noncopyable
design or evidence that performance is not going to be impacted by
ref-counting. Again, look at this from the design criteria of the
C++ language. You should pay for only what you use.
