I think this is by definition impossible -- if you are subclassing it, you are changing its behavior is *some* way, which way will determine how you want it it behave under all the various conditions that an array may encounter. So there is no subclass that handles all these issues, nor is there any pre-defined definition for correct. My personal use for subclassing has been to plug in a new object into code that was currently using a regular old numpy array -- in that case, all it needed to handle were the use-cases it was already being used in -- so running my test code was all I needed. But if I were startting from scratch, I'd probably use the "has a" rather than the "is a" OO model. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
