But if it did it that way, the condition (init-form) would only be
evaluated once, and I’d find *that* counterintuitive. Consider the
usual form of a while loop:

    (while-let ((run (some-condition)))
      (message "running"))

Do you expect that to evaluate (some-condition) once, then, if it’s
initially true, run forever?
