This is a method on the generic function compute-applicable-methods.

This method signals an error if any method of the generic function has a specializer which is neither a class metaobject nor an eql specializer metaobject.

Otherwise, this method computes the sorted list of applicable methods according to the rules described in the section of the CLOS Specification called ``Method Selection and Combination.''

This method can be overridden. Because of the consistency requirements between this generic function and compute-applicable-methods-using-classes, doing so may require also overriding compute-applicable-methods-using-classes (standard-generic-function t).
