break does not execute when not given an argument

[Nodnarb12500]

(defvar x 0)

(while true
  (println x)
  (set x (+ x 1))
  (if (> x 4)
      (break)
  )
)

just runs forever

if you give it a variable it also doesnt execute

(defvar x 0)

(while true
  (println x)
  (set x (+ x 1))
  (if (> x 4)
      (break x)
  )
)

continues running forever
