13.1.6 Generic Function Invocation Protocol

compute-applicable-methods-using-classes is not implemented.

compute-discriminating-function is implemented and does return the discriminator but not through compute-applicable-methods-using-classes since LispWorks does not have that function. Moreover add-method does not call compute-discriminating-function because this would be inefficient when doing multiple calls to add-method . Instead, compute-discriminating-function is called when the generic function is called.
