That's pretty horrible. So now I need to keep track of the 
implementation of my members to figure out whether it is okay to skip 
the destructor or not.

All of this from a language that claims to support RAII, which was 
invented precisely so the programmer does not have to keep track of 
those things.

I think this is precisely the sort of corner cases that drive people 
away from C++.
