I'm new to Lua, so maybe there is already something like this.

If I make my own Lua objects with several Metatable entries, my understanding is that I will have to add these entries for every object. If I have a lot of these object, that seems wasteful, and adds overhead from extra memory accesses. I was thinking, how about having a metatable entry called "__inherit", which is just a reference to another table, and which is checked if a given entry is not found?
