It's in Behavior. The hierarchy for Array and Array class looks like:
Instance Protocol Class Protocol
----------------------------------------------------------
Array Array class
Arrayed Collection Arrayed Collection class
Sequencable Collection Sequencable Collection class
Collection Collection class
Object Object class
(nil) Class
ClassDescription
Behavior
Object
(nil)
You can find this by doing a "spawn protocol" in the class browser pane
when the switch is set to Class (to see the class protocol as opposed to
the instance protocol).
