true. but the pointer to it isn't

and i was talking of a const char * kwlist[] { }
obvious optimization is to declare kwlist as static. but when the module
is loade, kwlist gets initialize. adding another const tags the whole
kwlist as const and then totally readonly. therefor, your compiler is
able to store kwlist (the array) in a RO segment.
