PiL2 says this:

  From the user point of view, a module is a library that can be loaded
  through require and that defines one single global name containing
  a table. Everything that the module exports, such as functions and
  constants, it defines inside this table, which works as a namespace.
  A well-behaved module also arranges for require to return this table.

Also, the 'module' function follows this behavior.
