Well, in Python you can invoke any function with your own context (globals
and locals).   Zope may supply its own globals when it calls an external
method , and maybe in some cases that would prevent yours from being known.
It's an area I don't know much about.  I'd still prefer to pass everything
as explicit parameters, but I can see cases where it would be useful to use
various global variables.

How are you making use of your myGlobals module? Just importing * from it?
