Same as all C++ handles; prevent dangling references. C++ handles are the
equivalent of Java references. Value semantics are better when they're
possible, but if the alternative is noncopyability and raw pointers, I
always prefer the handle approach. Not all C++ programmers agree. A
construct on which Java is built upon must be evil. :-)
That said, in this case I think that the hybrid approach is better than the
two other alternatives.
