Yeah, I suspect the real lesson here is don't use objects at all.
They are rarely as useful as people make out, and most uses of them
seem to be because lesser languages lack good compiler checks on
variants.  After all, there's no real problem at all spreading match
statements around the program if I can be sure that the compiler will
highlight everywhere which needs to change when I change my variant.
