[Python-ideas] Python docs page: In what ways is None special

[Neil Girdhar]

Is None a builtin?

In [1]: from keyword import kwlist

In [3]: 'Ellipsis' in kwlist
Out[3]: False

In [4]: 'None' in kwlist
Out[4]: True

Maybe we should change
This type has a single value. There is a single object with this value. 
This object is accessed through the built-in name None. It is used to 
signify the absence of a value in many situations, e.g., it is returned 
from functions that don’t explicitly return anything. Its truth value is 
false.
