Write a modding API where you use

get_inventory_item(something, slot) -- aka a "static non-replaceable 
function"

And "get_inventory_item" cannot be replaced and you don't call a 
function from "something" through it. So e.g. no

function get_inventory_item(something, slot)
  return something.get_inventory_item(something, slot) -- aka an 
"object function"
end

And no having a lookup table to map objects to functions.
