Me: Dear #Python I'd like a dict that is immutable, as immutable objects are nice and safe to use; Python: Why don't you use types.MappingProxyType? Me: It's not Pickleable; Python: Wait some time and use ``frozenmap``; Me: It does not support O(1) operations; Python: Why don't you roll your own? Me: 🤦♀️
I'll download some implementation from PIP, don't worry. But I'm mildly irritated that I need.
