BS! You can inject symbols into sys.modules and achieve a
true global.

    ## BEGIN: INTERACTIVE SESSION ##
    py> import sys
    py> def foo():
    ...     print 'My name is foo'
    py> sys.modules['__builtin__'].__dict__['foo_func'] = foo
    py> foo_func()
    My name is foo
    ## END: INTERACTIVE SESSION ##
