	tuple_object:pairs(), tuple_object:ipairs()
	In Lua, `lua-table-value:pairs() <https://www.lua.org/pil/7.3.html>`_ is a method which returns: ``function``, ``lua-table-value``, ``nil``. Tarantool has extended this so that ``tuple-value:pairs()`` returns: ``function``, ``tuple-value``, ``nil``. It is useful for Lua iterators, because Lua iterators traverse a value's components until an end marker is reached.
	``tuple_object:ipairs()`` is the same as ``pairs()``, because tuple fields are always integers.
	return
	function, tuple-value, nil
	rtype
	function, lua-value, nil
	In the following example, a tuple named ``t`` is created and then all its fields are selected using a Lua for-end loop.
	tarantool> t = box.tuple.new{'Fld#1', 'Fld#2', 'Fld#3', 'Fld#4', 'Fld#5'} --- ... tarantool> tmp = '' --- ... tarantool> for k, v in t:pairs() do > tmp = tmp .. v > end --- ... tarantool> tmp --- - Fld#1Fld#2Fld#3Fld#4Fld#5 ...
