Subject: Determining a class's ancestor easily without instances

Given two classes A and B, I know that I can loop through the 
superclasses of A to determine it it's a descendant of B.

Is there a more expedient way to do this - something like "is_a?" but at 
the class level (since is_a? is for objects)?

Thanks,
Wes
