If the function is declared with "object" as return type (or nothing which defaults to the same thing), then Cython will interpret that as the function handing away the reference of the object and make sure it is decref-ed. -- Dag Sverre _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
