The standard mentions assignment and copy ctor when it has something
to say about their semantics.  The assumption (as documented in 
chapter 17) is that if you do something under the hood that would
make the compiler-generated version do the wrong thing, it's your 
responsibility (as implementor) to cover up by defining one that 
works right.
