The less-familiar parts of Lisp for beginners — method-qualifiers

Now we move to the method-qualifiers function.  This is another example of a function useful in the implementation of Lisp, specifically in the dispatching of methods.  It allows the programmer to distinguish between primary methods, :after methods, :before methods, and :around methods.  While there is likely to be a programmer who has a use for this, I cannot think of a situation where manually dispatching methods is necessary.  The Lisp generic function system, augmented by define-method-combination, seems suitable for any case I can imagine at the moment, so I believe you’re unlikely to find yourself needing to make use of method-qualifiers.
