In the default tip (3.3a2+), importlib.__import__ is already bootstrapped, so you don't need mess with anything. As well, in any of the 3.x versions you can bind builtins.__import__ to importlib.__import__. If you are making changes to importlib (essentially, changes in Lib/importlib/_bootstrap.py), you must re-build (make) cpython in order for your changes to get pulled into the frozen copy of importlib. Until you do that, the built-in import machinery will be the one that existed before your changes. You could also re-bind builtins.__import__ to try out the changes without having to re-build, but ultimately your changes will have to get frozen (into Python/importlib.h) and will be part of the commit of your changes to importlib. Likely you already know all this, but just in case... :) -eric _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
