Re: [Cython] [cython-users] Recommendations for efficient typed arrays in Cython?

Distinguishing between Python and C types would be problematic anyway, since a PyObject* is both a Python type *and* a C type. Really? The way I see it, "object" is a Python type and "PyObject*" is a C type. That is, PyObject* is just a raw C pointer with respect to behavior.

Well... while it's possible to declare something as PyObject* in Cython and get raw pointer behaviour, it's something you should only do in very rare circumstances, because you're then totally on your own when it comes to reference counting and exception handling. If you're suggesting that 'def object foo' should give Python reference semantics and 'cdef object foo' raw C pointer semantics, that would lead to a world of pain. -- Greg ___ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
