If it works, then no, no problem. distutils may balk at building your extension, though. >>> It doesn't look like using ctypes would be an option, as my goal is to >>> 'vectorize' some operations. >> You mean you need to use PyMultiIter objects for broadcasting?

That's why I need the extension. ctypes would be an option, then. You would just do the loop in C. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
