The biggest issue I hit when adding Lua 5.3 support to CorsiTH was that floating point numbers now crash when sent to a C function that expects a lua_Integer whereas before they would be silently truncated. Since we still support 5.1 as well I ended up scattering a lot of math.floor to compensate. That said it was trivial compared to the _ENV change for 5.2
