Pallene and Teal are in a bit of a different space. Teal is focused on compile-time type checking. The intention is to encourage you to add type annotations to your entire Lua codebase. It's another take at the problem that Typed Lua was trying to solve. A Typed Lua 2.0, if you want to call it that way. Pallene, on the other hand, is more focused on performance. The tradeoff is that it doesn't cover the entirety of the Lua language, just the features that we can generate fast code for. The intention is that you can write the performance-critical parts in Pallene and glue everything together using Lua (or Teal). That said, I certainly wouldn't be surprised if we saw more cross pollination of ideas between these two languages in the future :) |

We definitely like to encourage the use of types (we <3 types!), but, just to clarify, Teal does support hybrid Lua/Teal codebases well, by use of definition files a la TypeScript. The Teal compiler itself is currently a "main program" written in Lua and the "core compiler" written in Teal. :)

please don't, people are already confused as is. :)
(For those not well-versed in Lua history like Hugo and me :), "Typed Lua" was an earlier academic project, which had different design criteria such as being able to type check unannotated "idiomatic" Lua, which made it a much more interesting research project and a much more difficult industrial one — Teal is very pragmatic, with the intention of being immediately usable but no intention of being academically interesting, more in the TypeScript mindset. This talk goes through the history, for those interested: https://www.youtube.com/watch?v=VUThGgxOf28 )

For sure! There are some exciting possibilities there!
