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.
