I'm a simple Lisp guy who wonders if it is be possible to add some kind
of macros to the language. Then features like this could be added by
anybody. Lisp people do this all the time and there is no need for
feature requests or any discussions.

    (with-returns
       ;; some code
       (return-if foo)
       ;; more code
       (return-if bar))
