The function (even a closure) would be fully recreated on deserialization, it is fully safe to save it to disk. It wouldn't preserve reference equality -- it would be a new function -- but the behaviour and the state (if using closures) would be equivalent.

I didn't include asserts in the linked case, because I thought it would be too verbose. You can see asserts in the test, that is linked below the example. Maybe it was the wrong call, I will think about including asserts into the example itself.

That's super cool

I think you could make it clearer, try reading the readme as someone with the preconceived notion that this is Yet Another Lua Serializer that translates functions, userdata and threads to their tostring() output. There are hundreds of those projects
