…path (python#10495) * bpo-32492: 2.5x speed up in namedtuple attribute access using C fast path * Add News entry * fixup! bpo-32492: 2.5x speed up in namedtuple attribute access using C fast path * Check for tuple in the __get__ of the new descriptor and don't cache the descriptor itself * Don't inherit from property. Implement GC methods to handle __doc__ * Add a test for the docstring substitution in descriptors * Update NEWS entry to reflect time against 3.7 branch * Simplify implementation with argument clinic, better error messages, only __new__ * Use positional-only parameters for the __new__ * Use PyTuple_GET_SIZE and PyTuple_GET_ITEM to tighter the implementation of tuplegetterdescr_get * Implement __set__ to make tuplegetter a data descriptor * Use Py_INCREF now that we inline PyTuple_GetItem * Apply the valid_index() function, saving one test * Move Py_None test out of the critical path.
