2020-01-30 Thread STINNER Victor
STINNER Victor added the comment: Once I discussed with Eric Snow during a core developer sprint: _Py_IDENTIFIER() should use an "interpreter local storage" for identifiers values. _Py_IDENTIFIER() would only be a "key" and _PyUnicode_FromId() would store the value somewhere in a hash table
