CPython raise RuntimeError *by chance*. Detecting all invalid usage will increase runtime cost. So CPython may and may not raise RuntimeError. > I tried to reduce it to a simple example.

If you read C source code, you can expect when it happens. -- INADA Naoki <songofaca...@gmail.com> -- https://mail.python.org/mailman/listinfo/python-list
