EDIT (example):
Lets set simple empty table called "t" with metatable "mt":

local defaults = { a = "hello world" }
local mt = { __index = defaults } 
local t = {}
 
setmetatable(t, mt)

Now if you try:

d(t["a"])

It will print "hello world".
Key "a" is not present in table "t", but because we have defined metamethod __index in metatable, you will get value from "defaults" table.

If you try:

d(rawget(t, a))

It will print "nil", because rawget returns the real value without invoking any metamethod.
