[info-mcl] CLOS keeps on surprising me

[Toomas Altosaar]

Would have thought that the following would have been caught at compile time.
But I imagine that there is a good reason for only detecting this at run time.
This in 5.1b4.

(defgeneric some-function (x)
   (:method (x) (print x) (values))
   (:method :before (x) (print :before))
   (:method :after (x) (print :after))
   (:method :around (x)
            (print :around1)
            (call-next-method)
            (print :around2)
            (values))
   (:method :BULL (x)
            (print :BULL)))

;(some-function 5)

>  Error: #<STANDARD-METHOD SOME-FUNCTION :BULL (T)> is an invalid method.

>  While executing: CCL::%INVALID-METHOD-ERROR
