example:

test.lua

addressbook = {
	name = "Alice",
	id = 12345,
	phone = {
		{ number = "1301234567" },
		{ number = "87654321", type = "WORK" },
	}
}

modify test.lua with:

addressbook = {
	name = "Alice",
	id = 12345,
	phone = {
		{ number = "1301234567" },
		{ number = "87654321", type = "WORK" },
	},
	c = 3,     -- <-i'm here

I think it’s a feature , it raises an error when you put undefined fields into the table.

如果在项目中遵从这个特性，那么会需要额外定义一份专门用来序列化的table并赋值，而不是使用原有的table, 这样的消耗非常不划算
i must define another table for serialize data if i comply this rule in my project, it very low efficiency
