lispdoc - results for progn

(progn &rest forms)	Function: PROGN form* Evaluates each FORM in order, returning the values of the last form. With no forms, returns NIL.
Example: (defun bst-insert! (obj bst <) (if (null bst) (make-node :elt obj) (progn (bsti obj bst <) bst)))	Mentioned in: CLtL2 - 11.7. Package System Functions and Variables CLtL2 - 21.2.
