I can't guarantee there aren't problems (bugs) in the DIP, but I didn't find any 
more (the ones I did find Razvan fixed). If you're familiar with the C++ copy 
ctor, it is very similar, lending credence to the notion that there isn't a big 
problem left.

Regardless, we need to move forward with this, not wring hands wondering what to do.
