Description:

in contrast to other smalltalks, ST/X does not keep the classVariables
in a dictionary; instead, classVariables are stored as special globals,
with the className as prefix (colon-separated).
The reason is that stc-compiled code should be allowed to access classVars
in a similar fashion to globals.

Whenever a classes classPool is requested (by code imported from visualworks), 
an instance of myself is created, which forwards at: and at:put: messages 
to the original class. 
Notice that classPools are never asked for by smalltalk/x
code - especially not by the browser. However, imported code (like the refactory browser)
may do so.

This is an additional goody class; therefore:
