Me too! Me too! :P

Mostly based on Programming in Lua, 12.1.2 - Saving Tables with Cycles:

http://www.lua.org/pil/12.1.2.html

More alternatives:

http://lua-users.org/wiki/TableSerialization

Usage example for Data.lua:

local Data = require( 'Data' )

local a = {x = 1, y = 2, {3, 4, 5}}
a[2] = a -- cycle
a.z = a[1] -- shared subtable
a.f = function(n) return n+1 end

-- cross refs
local b = {k = a[1]}
a[3] = b

print( Data( a ) )


_[1]={}
_[1][1]=3
_[1][2]=4
_[1][3]=5
_[2]=_
_[3]={}
_[3]["k"]=_[1]
_["y"]=2
_["x"]=1
_ 
["f 
"]= 
f
