I guess Lua 5.2 already supports what you want:

  http://www.lua.org/manual/5.2/manual.html#lua_getlocal
  http://www.lua.org/manual/5.2/manual.html#pdf-debug.getlocal

  The first parameter or local variable has index 1, and so on, until
  the last active variable. Negative indices refer to vararg parameters;
  -1 is the first vararg parameter
