The repl will state that e.g. it doesn't understand Array.push-back! and other forms when they are used at the top level in non-functions:
(let [x (Array.push-back! &[1 2 3] 4)] x)
I did not understand the form `(deftemplate Array.push-back!)` at Array.push-back!.parameterizedTemplate:0:0.
Traceback:
(Array.push-back! (ref [1 2 3]) 4) at REPL:3:9.
(let [x (Array.push-back! (ref [1 2 3]) 4)] x) at REPL:3:1.
(do (Array.push-back! (ref [1 2 3]) 4) (str 4))
I did not understand the form `(deftemplate Array.push-back!)` at Array.push-back!.parameterizedTemplate:0:0.

The same error happens for interfaces too.
