This is in my previous message to the list, but since there seems to be (from my end, anyway) a long delay in list propagation, I'll repeat to you, Jeremy: The other problem is that without a patch, you can crash python with a mis-cased typo, as it tries to import the same module under two names: >>> import cStringIO >>> import cstringio dyld: python2.0 multiple definitions of symbol _initcStringIO /usr/local/lib/python2.0/lib-dynload/cStringIO.so definition of _initcStringIO /usr/local/lib/python2.0/lib-dynload/cstringio.so definition of _initcStringIO [ crash and burn back to shell prompt... ] instead of (with patch): >>> import cstringio Traceback (most recent call last): File "<stdin>", line 1, in ? ImportError: No module named cstringio >>> A .py module doesn't crash like a .so module, but it still yields two (or more) different modules for each case spelling, which could be the source of some pretty hard to find bugs when MyModule.val != mymodule.val. ( Which is a more innocent mistake than the person who actually writes two different files for MyModule.py and mymodule.py ! ) ---| Steven D.
