I am using a multimethod (demulti) that handles a couple of stuff, which for example it takes "string" or "number" and return accordingly. How do I create a method that returns something for everything else not handled? Like a default defmethod

defmethod f :default

btw if you're dispatching on types you can also use protocols

What do you mean?

something like (defprotocol PrettyPrintable (pprint [this])) (extend-type String PrettyPrintable (pprint [this] (clojure.pprint/pprint this))) (syntax is probably wrong but you get the idea) instead of (defmulti pprint (fn [obj] (type obj)))

@U02F0C62TC1 aside: type was enough, instead of (fn [obj] (type obj))
