   If it's not a null pointer, i don't see anything wrong with it.

   Well, here, mywidget.get() is a null pointer. But let's assume that   
   somewhere between defining mywidget and the function call, you make   
   mywidget to point to something, then, yes, this is perfectly fine.   
   Instead of   
      
     myfunc(*mywidget.get());   
      
   you could have also written   
      
     myfunc(*mywidget);

   What is the problem?
