List of slots for object?

[hall@aplcen.apl.jhu.edu (Marty Hall)]

Is there a general (non-PCL specific) way of getting a list of the
slots of an object? In PCL you can do 

(pcl::slots-to-inspect (class-of <object>) <object>)

but, to my embarrassment, I have been unable to find a general CLOS
method in Steele or Keene, but I probably didn't know where to look.
I assume there is a way, since "describe" would make use of it...

Thanks-
