Thanks for a wonderful book on Squeak.

The book discourages the use of Shared variables like Pool variables,
Class variables and Global variables. But it doesn't show how to avoid
them or when is the right time to use them. Specifically for me, when and
how to use or not to use Pool variables.

Thanks again,
Aik-Siong
