Hi,

Given the following class precedence where < denotes subclass:
C1 <C
C2 < C
C3 < C
        C11 < C1
        C12 < C1
        C13 < C1
        ...
        C33 < C3

Given a list L of instances belonging to cij, How do I  find the
ancestor A such that
(type-of O A) is true for all O in L, and there exists no O1< O that
satisfies this property?

Clearly this information has been computed by clos at some time when
computing the class precedence list. Is there some way of accessing
this information?

Thanks,

--Raman
