Argument Clinic generates invalid code for optional parameter if there are no mandatory parameters except self. Example:
/*[clinic input]
zlib.Decompress.flush
Return a bytes object containing any remaining decompressed data.
[clinic start generated code]*/
Generates:
... switch (PyTuple_Size(args)) { case 0: if (!PyArg_ParseTuple(args, ":flush", )) return NULL; break; ...Note a comma in PyArg_ParseTuple.

Good catch! It should be an easy fix, but I won't be able to get to it until tomorrow.

Here's a fix. Works for me, let me know if it works for you.

Georg, you mind reviewing this too? Six line patch. Just trying to clean my plate a little before I fix a bug for you :D
