Importlib somewhat does this already through a module's loader: http://docs.python.org/py3k/library/importlib.html#importlib.abc.PyPycLoader.bytecode_path . If you want to work off of module names this is enough; if importlib did the import then you can do __loader__.bytecode_path(__name__). And if it has not been loaded yet then that simply requires me exposing an importlib.find_module() that returns a loader for the module. Trick comes down to when you want it based on __file__ instead of the module name. Oh, and me finally breaking up import so that it has proper loaders or bootstrapping importlib; small snag. =) But at least the code already exists for this stuff. -Brett > > -- > --Guido van Rossum (python.org/~guido) > _______________________________________________ > 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/brett%40python.org > _______________________________________________ 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
