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
$
