You are serializing the function alone, and expect that the function is
serialized with its environment (ie, the current state of the

You could rewrite your serializing/deserializing functions to include
the environment of a function. Check out debug.getfenv() and
debug.getupvalue(), and maybe also debug.getlocal() and
