I could see how for buffers it would require at bit more work, but for C++ types that shouldn't be a problem. In particular, I'm looking at https://github.com/cython/cython/blob/master/Cython/Compiler/Parsing.py#L2615 - Robert _______________________________________________ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
