I'd love to have type annotations in Lua.

But this doesn't compile to Lua, right?

I found Teal, which seems to Lua what TypeScript is to JavaScript

I've used it successfully with Love2d projects (albeit with some quirks)

What are the quirks?

All of these, too: https://typescripttolua.github.io/docs/caveats

There are a great many implementations of Lua at this point, I'm aware of at least six. But Roblox upstreaming their semantic changes was never an option.

Just because there's a closed development model doesn't automatically imply the devs team lives and breathes "not-invented-here"-ism and are no interested in discussing improvements that make a difference to actual people using Lua in (extremely) large real world products.

> Lua is not "open developed". The development is done exclusively by the Lua team, at PUC-Rio. So, we do not need a SVN repository. Currently, we keep Lua with the good old RCS.

PUC-Rio Lua uses C (with a tiny bit of C++ for stack unwinding on errors if folks don't want to use `longjmp()`,) Luau is strictly C++. Luau rewrites quite a lot of the core structures, and they aren't compatible. Further, Luau is a fork of PUC-Rio Lua _5.1_ (the current is 5.4 I think?) and intentionally picks and chooses features from later Lua versions. Even things like improvements to the core VM interpreter loop wouldn't be upstreamable, because Lua 5.2+ has a fundamentally different model to allow for yielding in metamethods. PUC-Rio would not accept changes other than fixes for critical bugs in Lua 5.1.

I like both PUC-Rio Lua and Luau, but a hard fork with no upstreaming was the only option here. The architectural differences of the VMs are so large now that it would amount to PUC-Rio adopting Luau. Supposing there is some tiny bit that PUC-Rio is interested in, they can cherry-pick it out of Luau, since they use the same license.

If I had this as my message, and someone asked to ship changes, I would be more than mad.

just take the L dude.

really, dude?

Which would be the whole reason I would put such a statement there, in the first place.

What are you even trying to argue with now? That I'm not allowed to get angry in the hypothetical that I made up? Do you see why it's fruitless to continue arguing?

Or are you going to pick out some prior wording and analyse it further, because you just can't comprehend that corporations don't have best interests at heart, and some people prefer to just put things up and not deal with other people's improvements
