Why is this better than writing it out in plain Lua that everyome can
already understand?
I understand the intent is that it can express internal references (possibly circular) in a single literal instead of having to write the plain object and then imperatively link in the references using subsequent statements.
This could be implemented by a preprocessor that translates it into an IIFE that does exactly that.
