I just want to make a class as easily as I can with structs
(deftclass name a b c)
(defclass name nil ((a :initarg :a :reader name-a :type t) (b :initarg :b :reader name-b :type t) (c :initarg :c :reader name-c :type t))) (defun make-name (&key (a () #:a2071) (b () #:b2072) (c () #:c2073)) (make-instance 'name :a (if #:a2071 a nil) :b (if #:b2072 b nil) :c (if #:c2073 c nil))) (defun name-p (x) (typep x 'name))
The following are also supported
(deftclass (thing (:include x) (:conc some-) (:constructor gimme-thing)) a (b 0) (c 0 :type fixnum))
This also means it's easier to refactor into structs once you have done with experimenting.
