You can also use a proxy table to dynamically change the environment  
of functions you load/create:

local meta = {}
local env = setmetatable({}, meta)

local f1, f2
f1 = loadin(env, "r1=i+1")
in env do function f2() r2=i+2 end end

local vars = {i=1}
meta.__index = vars
meta.__newindex = vars
f1()
f2()
print(vars.i, vars.r1, vars.r2)
