(let* <bindings> <body>)

Syntax: <Bindings> has the form

((<variable_1> <init_1>) ...)

and <body> is a sequence of zero or more definitions followed by one or more expressions as described in section on lambda.

Semantics: The let* binding construct is similar to let, but the bindings are performed sequentially from left to right, and the region of a binding indicated by (<variable> <init>) is that part of the let* expression to the right of the binding. Thus the second binding is done in an environment in which the first binding is visible, and so on. The <variable>s need not be distinct.

(let ((x 2) (y 3))
  (let* ((x 7)
         (z (+ x y)))
    (* z x)))             ===>  70
