until

Arguments: condition &rest forms

Evaluates forms repeatedly until condition (which should be a Lisp form) evaluates to a true value.

The definition of until is

(defmacro until (condition &rest forms)
  `(loop (when ,condition (return)) ,@forms))

Note that loop surrounds its body with a block named nil (as used by the return form which is the consequent of the when form). This macro returns nil.

See also while.
