* * Execute Lua code, assuming that the code is located on

* result and convert it to the resp and reply ot the client.
*
* * Run Redis commands from within the Lua code (Including

*
* * Register Redis API to the Lua interpreter. Only shared

* (like debugging) are registered on eval.c).
*
* Uses script.c for interaction back with Redis.
