Never had any issues with this in real life, this is one of many 
things you should think about when modelling.

The real "problem" with C++ is that it both provides a lot of 
flexibility-for-responsible-designers, but also provides 
defaults. Since people don't write the default it is easier to 
forget to adjust the semantics of all member functions to the 
model.
