New submission from STINNER Victor:
I started to share some common identifiers in Python/pythonrun.c, extract:
/* Common identifiers */
_Py_Identifier _PyId_argv = _Py_static_string_init("argv");
_Py_Identifier _PyId_builtins = _Py_static_string_init("builtins");
...
Do you think it would be interesting to continue to share such identifier
somewhere? Maybe in a new file?
We might do the same for some common strings like empty string, single
character (like "\n"), etc.
See also issue #19514.
