-- Access inside table over __call
-- This is a very nice access since it only can be called over <this>()
function newT()
   -- create access to a table
   local _t = {}
   -- metatable
   local mt = {}
   mt.__call = function()
		  -- hold access to the table over function call
		  return _t
	       end
   return setmetatable( {},mt )
end

-- Access inside table over commonly used variable self[self], inside __index
function newT2()
   local t = {}
   local mt = {}
   mt.__index = {
      [t] = {}
   }
   return setmetatable( t,mt )

-- Access inside table over nomal variable
-- disadvantage is that setting a key to _t will override
-- the access to the hidden table
function newT3()
   local mt = {}
   mt.__index = {
      _t = {}
   }
   return setmetatable( {},mt )
end

-- Access over nomal variable inside table
function newT4()
