I still hope for a day where Lua is implemented into browsers themselves, though this would set off the whole "but VBScript" arguments again, but at least Lua is pretty much standardized and it can be compiled almost everywhere. Not sure how much it would or wouldn't compliment the browsers DOM and such though. If it were added just on experimental browsers just to test it out and see it's upsides and downsides that would be great too, maybe in Electron or Nw.js somehow?

I'm sure I'll get critical comments on this but it beats compiling Lua to JS to make it convert itself back to JS. Maybe WebASM will be a solution for this, but it's too soon to tell for me how reliable that is for now.
