ideas for detecting which type of clojure (jvm, clr, js) is at remote end of the repl

gistfile1.txt

; idea 1 - works if repl's read configured to support reader conditionals
  #?(:clj :clj :cljr :cljr :cljs :cljs)

; idea 2 - may work - note that order is important below
  ; send this first
  ; if the result is non-nil, dealing with cljs, don't continue
  (resolve '*clojurescript-version*)

  ; only send the following if the previous result was nil
  ; if the result is non-nil, dealing with clr, don't continue
  (try
    (import 'System.Object)
    :cljr
    (catch Exception _
      nil))

  ; only send the following if the previous result was nil
  ; if the result is non-nil, dealing with jvm, don't continue
  (try
    (import 'java.lang.Object)
    :clj
    (catch Exception _
      nil))
    
  ; if the previous was nil, don't know what we're dealing with
    
  ; N.B. trying to check jvm before clr may not work well as
  ; the clr repl doesn't appear to get along that well with the
  ; code to check for the jvm
