I attached a small patch to solve part of the problem of the missing parent initialisation: I call Parent.__init__ and ParentWithGens.__init__ explicitly, during initialisation of a ring. In that way, the __init_extra__ methods are correctly picked up.
However, that does not solve the performance problem.
Question one: How can one come to speed?
Question two: Is my patch really trivial enough to be called a referee patch?
