Other source files defining globals is not very modular. I tend to take
advantage of the (rather unique) feature of Lua "dofile" that allows return
values.

I'd much rather load a complex number package (for example) using:
    complex = dofile("complex.lua")

than the global version
    dofile("complex.lua")

The file "complex.lua" has:
  local c = {}
  function c.add ... end
  function c.sub ... end
  etc

  return c
