Lua Oito (Lua8)

[clsource]

Hello I created a fork of lua (https://github.com/NinjasCL/lua8) to address the issues described here

libretro#2

also added additional sugar like compound assignments (+=) and C like comments to save some tokens.

I think this could be added not as a replacement for lua, but as an alternative language. Because if lua is replaced with this version, many new games could not be retro compatible with older tic 80 versions thanks to syntax differences.

Maybe some trick can be added to use this lua version but differenciate between iso lua and oito lua so carts can be retro compatible and syntax colouring can be different.
