Syntax:
destructuring-bind lambda-list expression declaration* form*
=> result*
Arguments and Values:
lambda-list---a destructuring lambda list.
expression---a form.
declaration---a declare expression; not evaluated.
forms---an implicit progn.
results---the values returned by the forms.
Description:
destructuring-bind binds the variables specified in lambda-list to the corresponding values in the tree structure resulting from the evaluation of expression; then destructuring-bind evaluates forms.
The lambda-list supports destructuring as described in Section 3.4.5 (Destructuring Lambda Lists).
Examples:
(defun iota (n) (loop for i from 1 to n collect i)) ;helper
(destructuring-bind ((a &optional (b 'bee)) one two three)
`((alpha) ,@(iota 3))
(list a b three two one)) => (ALPHA BEE 3 2 1)
Affected By: None.
Exceptional Situations:
If the result of evaluating the expression does not match the destructuring pattern, an error of type error should be signaled.
