/*  
>>> Number each instance of type <<<

Expected to receive these calls in order:
    IFoo#1.Zap()
    IBaz#1.Gloop(1)
    IFoo#2.Zap()
    IFoo#1.Bar()
Actually received matching calls in this order:
    IFoo#1.Zap()
    IFoo#2.Zap()
    IBaz#1.Gloop(1)
    IFoo#1.Bar()

**** Disadvantage: 
****     what to do with subs that implement multiple interfaces?
****     Number is overloaded - number of calls or instance number?
**** e.g. Sub.For<IFoo,IBaz>();


>>> Identify substitutes in order <<<

Expected to receive these calls in order:
    sub0: IFoo.Zap()
    sub1: IBaz.Gloop(1)
    sub2: IFoo.Zap()
    sub0: IFoo.Bar()
Actually received matching calls in this order:
    sub0: IFoo.Zap()
    sub2: IFoo.Zap()
    sub1: IBaz.Gloop(1)
    sub0: IFoo.Bar()

**** Advantage: Get to use "subzero" in an exception. Flawless, victory.
**** Disadvantage: difficult to compare?

>>> Identify substitutes in order with descriptive message <<<

Expected to receive these calls in order:
    IFoo.Zap() called on substitute 0
    IBaz.Gloop(1) called on substitute 1
    IFoo.Zap() called on substitute 2
    IFoo.Bar() called on substitute 0
Actually received matching calls in this order:
    IFoo.Zap() called on substitute 0
    IFoo.Zap() called on substitute 2
    IBaz.Gloop(1) called on substitute 1
    IFoo.Bar() called on substitute 0

**** Disadvantage: awful


>>> Identify substitutes in order via a non-numeric reference <<<

Expected to receive these calls in order:
    IFoo a.Zap()
    IBaz b.Gloop(1)
    IFoo c.Zap()
    IFoo a.Bar()
Actually received matching calls in this order:
    IFoo a.Zap()
    IFoo c.Zap()
    IBaz b.Gloop(1)
    IFoo a.Bar()

**** Advantage/Disadvantage: I don't even know
