    If A is a member variable there *are* performance benefits. With statement is transformed to this

    Code:
    Dim __hidden_A As __TypeOfA
Set __hidden_A = A
__hidden_A.B = 1
__hidden_A.C = 2
__hidden_A.D = 3
    Because __hidden_A is on the stack while A is actually this->A (a member variable) there are several instructions (or more) saved.
