     Get rid of globals. Make the root classes elements of the special
objects array (Object already is), and look up classes through that.
Make everything else that used to be a global (like Transcript) the
responsibility of some class, and use them by sending messages. This
also makes the modularization straightforward.

     There's no need for a system dictionary. It was a profound and
long-lived mistake.
