I guessed as much :-). I should probably have put him on CC.

If a patch is welcome, I might look into that.

Oh, that is a good idea. According to my test, CLOS does not create a wrapper by
default, so hiding that behaviour behind `eieio-backward-compatibility'
seems like what I would want to aim for.

I was actually trying that at first, but it turned out I need
inheritance based dynamic dispatch. So I am actually very grateful for eieio
being merged into Emacs proper, `defclass' *is* handy if you need its
power.
