metaclasses

[<CHEEWEEI%ITIVAX.BITNET@CUNYVM.CUNY.EDU>]

In defining a metaclass eg.

(defclass my-standard-class (standard-class)
   ())

I also have to define:

(defmethod check-super-metaclass-compatibility ((x my-standard-class) (y t)) 't)
Is this something that must be done now as well as in future for user
defined metaclasses?
Is the decision when classes and methods are compiled totally left up to
the CLOS implementation? Is there a similar function like
compile-flavor-methods in Flavors that ensures it?
