a method's return value type in a derived class be different from the base  
class?

Assume Class2 inherits Class1.
Is this OK:?

In Class1:
Public func(a As Integer) As Integer
End

In Class2:
Private func(a As Float) As Float
End

When running func() on either a Class1, or a Class2, only the method in  
Class1 will be invoked, because it is public and the other is private.

Or, easier said: Are private symbols affected by inheritance rules at all?
