The initialization code of all modules must have been run
before running any module's main code. This should have been
fixed quite a while ago as part of another CL but somehow
wasn't.

In the process of fixing it now, I'm also moving the initialization
phase out of Evaluate into Instantiatiate. This corresponds more
closely to the specification and avoids confusion.
