I'm not sure what "it's" is referring to in your statement. In 
the example, Foo wraps manually allocated memory that is freed 
when Foo goes out of scope. If the goal is to free the memory in 
Foo when Bar goes out of scope, that can be done without error by 
rewriting Foo. Therefore I'm not understanding how this situation 
can arise in real world code (I'm sure it can, though, which is 
why I'm asking).
