Did you mean dynamic compilation? I see this problem as manageable if
you're okay with not sharing the upvalues:

for i = 1, n do
  <code>
  local f = load("local i = ...; return function (...)"..text.." end")
  f = f(i)
  <code>
end

You can also go to the trouble of using the debug library to
automatically create and set the locals. If you're using Lua 5.2, you
can of course join the upvalues as well.
