That sounds very far-fetched. You're pretty much designing a new language variant. It's not an argument for burdening the original

Yeah, that's what we do ;)

You should be able to prototype what you want using an advisory subclass (if you subclass dict and add slots=[] to it, it will cost very little overhead) or using a custom extension that implements the flavor of frozendict that works best for you -- given that you're already using greenlets, another extension can't be a bid burden.

I understand. The only reason I wrote about it is to give an idea of how frozendicts may be used besides just sandboxing. I'm not strongly advocating for it, though.
