In general, finalizers are for cleanup of resources that are NOT memory resources. A plain table only uses memory resources, but it may reference objects that do (userdata, cdata). Finalizers should be attached to these objects, not to the containing table. An assumed need to attach a finalizer to a table is often misguided and the overall data structure design should be reviewed. There are very few valid reasons to do this, which is why there has been no pressing need to implement finalizers for plain Lua tables. Like all finalizers, it has it's hidden costs. --Mike
