If you're worried about supporting older Python versions then the simplest thing is probably to just implement the __array_interface__ or __array_struct__ interface. They're pretty trivial, and while not as standards-compliant and Correct as PEP3118, they'll work just fine with numpy across any version of Python. (Of course you can also implement both PEP3118 and __array_struct__ together.) http://docs.scipy.org/doc/numpy/reference/arrays.interface.html -n _______________________________________________ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
