I am currently working on the Ironclad project porting numpy to Ironpython. It would be quite useful for me if HermitianTestCase in test_linalg.py was a new style-class instead of an old-style class - since Ironpython has a bug where dir operations do not work for classes inheriting from both old- and new- style classes and I'd very much prefer not to patch my version of numpy. In general, it would be useful if whenever this multiple inheritence pattern is used new-style classes are used rather than old style classes. This would require the following classes to change: test_numerictypes - create_values, read_values_plain, read_values_nested test_print - create_zeros, create_values, assign_values, byteorder_values test_io - Roundtriptest test_linalg - LinalgTestCase, HermitianTestCase Would people be ameniable to these change? Thank you very much for your help, Tom Wright
