Maybe also properly separated list/array, map/dict and set types? The I-am-everything-{} type in lua is a bit unergonomic when you want to use it as only such a type and a stumbling block for unfamiliar users.

Can a project using 5.3 lua continue using existing .lua files but also write new files in .ljs?

Aren't match statements all the rage nowadays? Even C++20 get's one (with a silly name, of course)!

Finally, setmetatable is nice, but, yes, "proper" not handrolled classes.

Too few scripting languages have these. Do you intend to make this include interior mutability as well or is this only pointer deep?

The general idea is to be able to reuse code as much as possible, and C/C++/Java/Javascript style syntax make a lot of code available and if we ditch the 1 based index in favor of 0 based it makes it even easier.

It looks like it's still 1-based currently, is that right? 1-based arrays have been the biggest obstacle to me using Lua.

I did years of assembly, then C, and now Lua. I've yet to find the 1-based indexing to be an issue, and that's even having written a few C modules to manipulate Lua arrays. What is it about the 1-based arrays that is so off-putting?

Again the point is easy code reuse.

Yes you are right it's still 1 based to allow easy conversion from actual existing Lua projects.
