Because STklos has a metaobject protocol, every STklos class is an
object on which you can invoke methods. Two of the more useful methods
on class objects are class-direct-slots and class-slots. So if I
have the following classes
(define-class <A> ()
((x :initform 0)
(y :initform 1)
(z :initform 2)))
(define-class <B> (<A>)
((u :initform "hi")
(v :initform "there")))
I can make method calls, like in the following expressions:
(class-direct-slots <B>) ===> ((u :initform "hi") (v :initform "there"))
(map symbol->string (map car (class-slots <B>))) ====> ("x" "y" "z" "u" "v")
Hope this helps.
