- Try

- 	self class superclass

- to get the name of the superclass,
- Don't have a clue on how to get at its class-pool though.

Class "Class" implements the methods "sharedPools" and "allSharedPools",
which respond with a Set of the names of the pools that are specified
in the receiver or in the receiver and all its superclasses, respectively
(cf. Goldberg and Robson, Smalltalk-80: The Language and Its Implementation,
p 276).

Each pool is a Dictionary, so once you know the name of a pool, you can
send the pool the message "keys", which responds with a Set of the names
of its keys.
