lispdoc - results for let* 

(let* bindings &body body)
Function: LET* ({(var [value]) | var}*) declaration* form* Similar to LET, but the variables are bound sequentially, allowing each VALUE form to reference any of the previous VARS.
Example:
(defun make-image ()
  (let* ((name (create-name))
         (i
          (make-instance 'photo-image :name
                         name)))
    i))

(alexandria.0.dev:when-let* bindings &body forms)
Function: Creates new variable bindings, and conditionally executes FORMS. BINDINGS must be either single binding of the form: (variable initial-form) or a list of bindings of the form: ((variable-1 initial-form-1) (variable-2 initial-form-2) ... (variable-n initial-form-n)) Each initial-form is executed in turn, and the variable bound to the corresponding value. Initial-form expressions can refer to variables previously bound by the WHEN-LET*. Execution of WHEN-LET* stops immediately if any initial-form evaluates to NIL. If all initial-forms evaluate to true, then FORMS are executed as an implicit PROGN.
