So take this definition from master:
(def
^{:arglists '([x])
:doc "Return true if x implements ISeq"
:added "1.0"
:static true}
seq? (fn ^:static seq? [x] (instance? clojure.lang.ISeq x)))
static is used twice here. What is / was the difference? Is it correct
to say that it is now just noise in the code and could be stripped
away? Is it correct to say it has nothing to do with 'dynamic',
contrary to what the last SO post in the topic you linked to implies?
