-- Sets or Arrays
-- RST
-- .. function:: array_combine(arrays)
--
-- Takes all arguments which must be Lua Arrays (that is tables with integer
-- keys starting with index 1) and combines them into one single array.
-- This is must useful to combine arrays of Fields.
--
-- :arg arrays: any number of arrays
-- :returns: a new array with all values of all arguments
function array_combine(...)
local t = {}

for _,v in ipairs(arg) do

-- RST
-- .. function:: array_reverse(a)
--
-- Returns an array with the same values in reverse order
--
-- :arg a: One array object
-- :type a: :class:`array`
--
-- :returns: array with values in a in reversed order
function array_reverse(a)
