I think, there's no need to.  Now I understand :)

There was no ampersand in my version before coord.  I thought that as
coord is already a pointer, PyArg_ParseTuple will want it, not the
pointer to the pointer.

Now it works, but I will of course change it to get the simpler
parenthesised version as in your Example 1.

Great thanks :D
