See for example this code:

function round(v, step)
    return math.tointeger((v + step*0.5) // step * step)
end

This is already supported and tested:

luaparse/luaparse.js

Lines 775 to 779 in d61c6fe

	case 47: // /
	// Check for integer division op (//)
	if (features.integerDivision)
	if (47 === next) return scanPunctuator('//');
	return scanPunctuator('/');

Lines 35 to 40 in d61c6fe

	// { "luaVersion": "5.2" }
	a = 1 // 0 -- FAIL
	a = p ~ q -- FAIL
	a = p & q -- FAIL
	// { "luaVersion": "5.3" }
	a = 1 // 0

Ace will have to enable the "luaVersion": "5.3" option.
