Hm, ok - maybe something like this:

(dolist (class (sb-mop:class-direct-subclasses (find-class class)))

Yup, that's the kind of thing I was looking for, thanks. Actually,
I'll use class-direct-SUPERclasses to go up the hierarchy, and also filter out
(find-class 'standard-object) from the check list. But that's the idea.

If you really need the list of all direct and indirect superclasses, you can simply call class-precedence-list. (This may only work when the class is already finalized, that is, roughly when an instance of that class already exists.)
