|bindings||list containing function definitions|
|body||program code in which definitions above are effective, implicit progn|
FLET is special form for local function binding. Bindings are not recursive and cannot refer to each other. Each binding contains function name, arguments, and function body. See LABELS, DEFUN, LAMBDA.
