Volatile Module templates

local M, module = {}, ...
...
function M.init(csocket)
    package.loaded[module]=nil
    ...
end
...
return M

Using: require("connector").init(c)

local module = _  -- this is a situation where using an upvalue is essential!
return function (csocket)
  package.loaded[module]=nil
  module = nil
  ...
end

Using: require("connector")(c)

Memory cleanup

Load some functions and at the end call init() !!! Otherwise our volatile modules won't work. Additionally there is a little improvement while assigning tmp to some function and then reassign it to nil.

tmp = require("basic_compile").compileAllFiles()
tmp = nil
require("basic_compile").init()
collectgarbage()
