closure/defmethod question

[Bruce Lester]

Do the Common Lisp rules regarding closures and functions (defun) apply to
CLOS structures created with defmethod and defclass?

The following code behaves as I expect (the value of A is available to
closure-test) in LispWorks:

(let ((a 5))
(defmethod closure-test ((i integer))
(format t "I:~A A:~A~%" i a)))

Is this behavior a core part of Common Lisp that would work in other Common
Lisp implementations?

According to _The Art of the Metaobject Protocol_, the :initform args
close over the environment of the defclass form. I assume that this is
a requirement also present in the ANSI CL standard.
