tp_base is *not* PyInt_Type, so I was wrong when I said that the dominant base was int. This is wrong IMO: tp_base should be int, for the type to be correctly initialized. Compare: >>> from numpy import * >>> print int_.__bases__, int_.__base__ (<type 'numpy.signedinteger'>, <type 'int'>) <type 'numpy.signedinteger'> >>> class C(signedinteger, int): ... pass ... >>> print C.__bases__, C.__base__ (<type 'numpy.signedinteger'>, <type 'int'>) <type 'int'> ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue5476> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
