Now that LLMs are a common thing for coding, modding communities (which in practice have a large number of people using Lua since quite a lot of the most widely modded games use Lua for mods) are having to adapt a bit to handle the influx of a huge number of mods from people who have never programmed before, which I tend to view as a good thing in the long run, but right now LLMs seem to be rather abysmal at writing reasonable Lua. There's a meme (in the original sense of the word) that you can tell when a mod is LLM generated because it will use pcall in ridiculous ways, seemingly because it's a lot quicker to abuse it as a retroactive control flow mechanism than to go back and add proper checks up front (and probably restructure the code in the process). Teal doesn't fully solve the underlying issue of LLMs apparently being very poorly trained on Lua but it does at least give a pretty good way of statically enforcing what the actual types it should be using are.
