let

• let is mostly equivalent to let*.

• Local variables defined by the same call to let can't depend on each other in the initialization clauses.

(let* ((x 0)

(y (+ x 5)))

(print y))

[prints 5, then returns 5]

(let ((x 0)

(y (+ x 5)))

(print y))

[behavior depends on

outside value of x]

Reference is to x outside of let
