[issue26822] itemgetter/attrgetter/methodcaller objects ignore keyword arguments

[Raymond Hettinger]

Raymond Hettinger added the comment:

In general there should be an early out test for keywords==NULL before calling the comparatively high overhead function _PyArg_NoKeywords.  

That function adds overhead everywhere it is used and provides zero benefit to correct programs in order to provide earlier detection of a very rare class of errors.

Some care needs to be taken before slapping _PyArg_NoKeywords onto every function in the core that doesn't use keyword arguments.
