Correction, the pseudocode for index resolution is closer to:

  function gettable_event(t, k)
    local value = rawget(t, k)
    if value ~= nil then
      return value
    end

    local mt = getmetatable(t)
    if mt == nil then return nil end
    local index == mt.__index

    if type(index) == 'function' then
      return index(t, k)
    elseif type(index) == 'table' then
      return index[k]  -- note that this is a recursion!
    end
    return nil
  end
