Thanks. No, I don't think there's an official way to accomplish that,
but let's create one. How about a new function that takes the buffer
request flags:
PyMemoryView_FromObjectEx(exporter, PyBUF_SIMPLE|PyBUF_WRITABLE)
If we can spare a new format code, this could be called directly in
PyArg_ParseTuple(), which would give back the memoryview.
Otherwise, you get the exporter from PyArg_ParseTuple() and call
PyMemoryView_FromObjectEx() manually.
If I'm not mistaken, this would save us the intermediate buffer on the
stack, and it's more readable.
