You're right. Here is the actual code I use for testing (badly transposed in 
my previous post):

"testmod.lua":
  local package = require "package"
  local original_module = module

  function module(modname, ...)
    original_module(modname, ...)
    package.loaded[modname].hello = "hello you"
    return m
  end

  require 'mymod'
  mymod.hi()

"mymod.lua":
  module 'mymod'
  function hi() print(hello) end

And the error I get is:
  lua: testmod.lua:11: attempt to call field 'hi' (a nil value)
  stack traceback:
          testmod.lua:11: in main chunk
          [C]: ?

Thanks for your insight,
Aladdin
