http://docs.python.org/c-api/typeobj.html#tp_getattro The Python documentation doesn't seem to say very if method/attribute slots are consulted before falling back to tp_getattro. If tp_getattro is consulted first, then implementing it will lead to a performance hit. I'd probably be +0 on providing recarray-like functionality on ordinary ndarrays, if it can be done without (significant) performance issues. -- Pauli Virtanen _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
