;; The Purrr language all by itself, without specialization to a real
;; machine, is at this moment only useful for debugging.

;; Since 'repl' can't run inside a parameterize env (this is because
;; of the use of toplevel forms), the only way to change what happens
;; to compiled code is to change the mode of the compiler.
