I didn't mean for all methods to be const. I meant that getters should be, 
especially if they are property getters (Q_PROPERTY).

The interesting thing is that, if the value it was getting were in the 
class itself (not in the d-pointer), the compiler wouldn't let you return 
it as a non-const. But the function's constness does not apply to the 
Private class's content -- just the pointer.

One other reason for the other recommendation: complex code should be in 
the Private class.
