As far as security is concerned, consider this example. I want to use erlang with lua. Those two are miles apart but not really when you boil everything down to a lua table. All containers are tagged tables such as having a metatable key saying 'tuple' or 'struct'. Then you serialize them back and forth via BIFs. Any value having a function will reject entire query. Furthermore a simple hash code can be forwarded after sending the data. The attacker would have to sync the client and server and make hash changes on both ends but since he cannot fuck with the server none of his tampering would work because it will be outright rejected. As far as transformer modules (aka configs) are concerned, they will be carried out AFTER the hash.
