read-eval-print loop

language, LISP, programming (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)))).
