I pinged Guido about this (he'll fire me if I ever do that again <wink>),
and he's really not keen on it.  "The right way" is to define a custom
metaclass instead (whose __init__ plays the role __class_init__ would have
played if defined in the class).  It makes sense to me, but I'll have to
play with it to be convinced it's as usable.
