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)))).
