I find it slightly disturbing the you cannot use dot notation when
referring to private properties within a class.  For example:

If a class has the following private properties:

Private Property Get CallCount() as Long
   Static x&
   x& = x& + 1
   CallCount = x&
End Property

Public Property Get Foo() as String
  ' This generates an error
   Foo = Format$(Me.CallCount,"000")

 ' but this does not
  Foo = Format$(CallCount,"000")
End Property
