Steve's basic premise is correct, but he's chosen the wrong
name to use. As Fredrik Lundh has written here
http://mail.python.org/pipermail/python-list/2002-June/109090.html
the name above is an implementation detail and one should
always do this instead:
import __builtin__
__builtin__.myname = "MyValue"
And doing so reinforces the idea that this is Almost Always
a Bad Idea. :-)
