I've had similar ideas in the past as we are doing dynamic code generation in PyPy, as well as in other projects. After some discussion with Armin i think there is another possibility for storing "source" or any other such meta information with code/module objects: make __file__ and co_filename instances of a subclass of 'str' providing an extra attribute. For a simple example, they could have a 'source' attribute, which could be tried first by appropriate inspect functions and traceback related functionality. We are about to test out this approach with the py lib (http://codespeak.net/py) and want to have it work for for Python 2.2, 2.3. and 2.4. I suspect there may be some issues lurking (also in your proposed PEP) especially with respect to encodings. Also we have some use cases where we want to retrieve source code from non-local locations and want to integrate this seemlessly with the introspection facilities of Python which obviously is an important part of the equation. I can report back if there is interest. cheers, holger _______________________________________________ Python-Dev mailing list [EMAIL PROTECTED] http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
