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)
(:method :BULL (x)
> Error: #<STANDARD-METHOD SOME-FUNCTION :BULL (T)> is an invalid method.
> :BULL is not one of :BEFORE, :AFTER, and :AROUND.
> While executing: CCL::%INVALID-METHOD-ERROR
> Type Command-. to abort.
See the Restarts menu item for further choices.
