extend Object in clj

[lilactown]

version

0.3.32 and master

platform

macOS / Clojure 1.11.1

problem

satisfies? in SCI does not properly discern between extending Object and the protocol not being implemented for the type.

repro

(defprotocol IFoo (foo [_]))
(extend-type Object IFoo (foo [_] :default))
(map #(vector (satisfies? IFoo %) (foo %)) [(Object.) "" 1 (make-array Long 3) inc true])

expected behavior

The above code should return the following:

([true :default] [true :default] [true :default] [true :default] [true :default] [true :default])

actual behavior

When run via bb, it returns the following:

([false :default] [false :default] [false :default] [false :default] [false :default] [false :default])
