Editing env, after loading a chunk.

Hey guys,
i wanna load a constructor with different environments. First, i thought something like that:

local sData = File.readAll()
sData = '_ENV = ...\n' .. sData
local constructor = load(sData, sName, 't', _)
local object = constructor(setmetatable({}, { __index = _ENV}))

but would brake with binary constructors. It is an advantage that the program has to read and compile the string one time.

My next idea was:

local sData = File.readAll()

local constructor = function (tEnv)
  return load(sData, sName, 't', tEnv)
end

Now, the program won't be decreased by reading the hard disk, but by compiling the string again and again.

Is there any possibility to use the first mentioned option without editing the string?
So:
local object = constructor(tEnv)

P.S. I don't want to use setfenv, because Lua 5.2 doesn't support setfenv

I believe not.

Maybe, i will use a buffer, to load constructors and edit the _ENV, after requesting one or
i will do something like term.redirect with environments.

Yes but it is a complicated procedure I'd rather not try and design. It would exploit meta-tables and locality.
