I was about to say "what, we've had records for decades" but then I read the changelog.

Interesting. I wonder if there a world where Elixir starts compiling maps to "native records"?

[out_of_protocol]

Probably going to be replacement rather than direct recompilement of structs. I imagine all sorts of corner cases are lurking around if you swap implementation around, e.g. if someone force-pushed unknown key into a struct at runtime. Would be nice to keep current struct syntax though with the only difference in declaration

probably not maps, but structs yes.

[s3cur3]

I dunno… it’d break a looooot of code if structs were suddenly not also maps. My bet is this becomes a new option you have to manually migrate to.

[dnautics]

Would it? I bet you could be very clever with transitional guards and the patching compiler to defensively handle both cases on detection of %{...}
