Patch #1691070 from Roger Upole: Speed up PyArg_ParseTupleAndKeywords() and improve error msg My tests don't show the promised speed up of 10%. The code is as fast as the old code for simple cases and slightly faster for complex cases with several of args and kwargs. But the patch simplifies the code, too.
