When pickle.py needs to import a module by name, it goes through a peculiar dance of
import(module, level=0) mod = sys.modules[module] As far as I can tell, unless builtins.import is overridden or sys.modules clobbered by user code, the above should be equivalent to mod = import(module, level=0)
Only for top-level modules:
import("distutils.core", level=0) <module 'distutils' from '/home/antoine/py3k/__svn__/Lib/distutils/__init__.py'> sys.modules["distutils.core"] <module 'distutils.core' from '/home/antoine/py3k/__svn__/Lib/distutils/core.py'>
Regards
Antoine.
