You are not forced to redefine the module function to do that. You may
do like that:

-- testmod.lua

function testmod(_M)
  package.loaded[_M._NAME].hello = "hello you"
  -- This line also works:
  -- _M.hello = "hello you"
  return _M
end

require 'mymod'
mymod.hi()

-- mymod.lua

module('mymod', package.seeall, testmod)
function hi()
  print(hello)
end

-------

And I get

$ lua testmod.lua
hello you
$
