Thinking about upvalues makes me wonder: is there any generic way to learn the size in bytes of a table in Lua? Since a table can have other tables or functions (or at least references to them) in it this is not a simple concept. Perhaps another way to ask this is: can I predict from within a program how much memory would be released if I cause a given object to go out of scope?
