I'd love to see a modern type system available as a Lua replacement. A couple things I didn't see skimming the docs: 1. Does it continue the billion dollar mistake (null)? 2. Does it allow type parameters so I can write a generic Map that works with any kind of keys and values?

If you're interested in "Lua with types", check out Teal aka "Typed Lua" aka "Tl": https://github.com/teal-language/tl https://github.com/teal-language/tl. It compiles to Lua and is available as a single-file Lua module.

  Alas, every type in Teal is nil-able, so it really is a TypeScript for Lua. Which is no small thing, but still, unfortunate.

    TypeScript guards against nulls with the flip of a flag. That's its biggest benefit in my opinion.

From my reading there is no null, and no generic types either.

Take a look at Nim, it's described as Python with types, but could be what you're looking for.
