|(language, LISP, programming)||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)))).
