read-eval-print loop

    (REPL) A programming structure
   within LISP which repeatedly reads a form from the user,
   evaluates it, and displays the result.

   A read-eval-print loop forms the basis of the Top-Level
   shell that programmers of the LISP family of languages
   interact with.

   In many dialects of LISP a very simple REPL could be
   implemented as:

   	(loop (print (eval (read)))).
