import module1
import module2 as m2
import module3, module4
from module5 import func1, func2
...
It works by declaring globals, not locals. Locals are allocated at compile-time (when Lua source becomes Lua bytecode). If require were made into a Python-like import it would be nice if it could support this form for declaring and assigning locals (your last example). My import.lua works mostly for the "make your own _ENV" way of doing that. In fact I almost want to call it table.import().~ hope that helps ~
