The py library (http://codespeak.net/py/dist/) already has a py.error module that provide an exception class for each errno. See for example how they use py.error.ENOENT, py.error.EACCES... to implement some kind of FilePath object: http://codespeak.net/svn/py/dist/py/path/local/local.py But I'm not sure I would like this kind of code in core python.
