Can someone give a strong rationale for a separate built-in class? Because "it prevents any unintended modifications" is a bit weak. If you have fixed keys, a frozen dataclass will do. If you don't, you can always start with a normal dict d, then store tuple(sorted(d.items())) to have immutability and efficient lookups (binary search), then throw away d. |
