Condition constructors in Common Lisp

#common-lisp #clos #conditions
TIL that I can do:
(define-condition my-condition () ())
(defmethod initialize-instance :after ((warning my-condition) &key)
(print "boo"))
The works on SBCL*, CCL, ECL, ABCL, CLISP.
*You need to use MAKE-INSTANCE
instead of MAKE-CONDITION
to make the constructor fire on SBCL. See https://bugs.launchpad.net/sbcl/+bug/1761735
