Z looks interesting for sure. It's a little limited though. But it would work fine for this use case.

Same. You can use Maybes and Eithers today with a package import. The barrier is getting people familiar with them. Right now there's a lot of push back against them just because of familiarity bias.

If the language adopted them as native though, people would jump on board.
