I am working on a program in Franz (Allogro) CommonLisp
using Flavors. I would like to be able to copy an instance
of a flavor. I would like the initial values to be the same,
but would like to be able to change the values in one without
affecting the other. Something like
(setq a (make-instance 'flavor :x 10 :y 20))
(setq b (send a :copy)) or (copy-flavor a)
(send b :set-x 5)
(describe a)
x:10 y:20
(describe b)
x:5 y:20
I can't figure out how to write this copy function.
The flavor may be a member of many super-flavors.
