Could frozendict or frozenmap be of some use for PEP 683 (Immortal objects)?

Well, as far as I know immortality was also suggested for interned
strings. If I understood well, the problem with "normal" strings is
that they are not really immutable in CPython. They have cache etc.
Also frozendict caches hash, but that cache can be easily removed.
