Yes, it is. I'm able to reproduce the problem. Christian

It's not just dir(). Same behavior with help(): Python 3.1a0 (py3k:67856, Dec 19 2008, 10:18:03) [GCC 4.0.1 (Apple Inc. build 5465)] on darwin Type "help", "copyright", "credits" or "license" for more information.

There are other ways to reproduce it without using dir, like range(10).__class__; hash(range(10)) Is there some reason no set tp_hash for rangeobject to PyObject_HashNotImplemented ?
