WRT #CommonLisp Object System (#CLOS):

The seminal book ›The Art of the Metaobject protocol‹ (1991, #AMOP) by #Kiczales, #Rivieres & #Bobrow demonstrates & discusses many design patterns for #ObjectSystem|s with #metaobject protocol, in which methods are not part of classes, due to #multimethod, #multipledispatch paradigms.

It also contributed much to #DylanLang.

Note that the #PrettyPrinting dispatch tables of #CommonLisp conceptionally are a #GenericFunction with #ParametricDispatch.

The function SET-PPRINT-DISPATCH is essentially an ADD-METHOD to the pretty printing parametric dispatch.

(Unfortunatly, the canonical, #ProofOfConcept implementation of PP by #RichardWaters is one single convoluted mess; basically a negative example of software design, even by standards of its time.)

You may want to consider the concept of #Prototypes with #MultipleDispatch (#PMD) by #LeeSalzman and #JonathanAldrich, as implemented in the #Slate programming language:
