 I think I've mentioned this before, but why not extend the programming
editor you use to do the expansion for you? I can certainly extend my
editor such that I highlight
	module5 func1 func2 func3
and have it (the editor) generate:
	local module5 = require "module5"
	local func1 = module5.func1
	local func2 = module5.func2
	local func3 = module5.func3
(or formatted however you like). No changes to Lua, you get exactly what
you want. Sure, if you "import" a library like "math" you'll get:
	local math = require "math"
	local abs = math.abs
	local acos = math.acos
	local asin = math.asin
	local atan = math.atan
	local atan2 = math.atan2
	local ceil = math.ceil
	local cos = math.cos
	local cosh = math.cosh
	local deg = math.deg
	local exp = math.exp
	local floor = math.floor
	local fmod = math.fmod
	local frexp = math.frexp
	local huge = math.huge
	local ldexp = math.ldexp
	local log = math.log
	local log10 = math.log10
	local max = math.max
	local min = math.min
	local modf = math.modf
	local pi = math.pi
	local pow = math.pow
	local rad = math.rad
	local random = math.random
	local randomseed = math.randomseed
	local sin = math.sin
	local sinh = math.sinh
	local sqrt = math.sqrt
	local tan = math.tan
	local tanh = math.tanh
but I see this as A Good Thing(TM)---you document exactly what you are
using and it's obvious to anyone using Lua what you are doing.
