As mentioned by others, you would need to reference them explicitly via _ENV. So, _ENV.print, etc.

It is already standard practice in Lua to have local references to globals:

local print, random = print, math.random

So you would just have to say

local print, random = _ENV.print, _ENV.math.random

I do not think that is that big a burden, and the benefit - immunity to typos - is huge.
