PyId_foo is a static variable, either on block level or file level. On first PyId_foo is a static variable, either on block level or file level. On first
usage, the string "foo" is interned, and the structures are linked. On interpreter usage, the string "foo" is interned, and the structures are linked. On interpreter
shutdown, all strings are released (through _PyUnicode_ClearStaticStrings). shutdown, all strings are released.
Alternatively, _Py_static_string allows choosing the variable name. Alternatively, _Py_static_string allows choosing the variable name.
_PyUnicode_FromId returns a borrowed reference to the interned string. _PyUnicode_FromId returns a borrowed reference to the interned string.
