Lua is scheme-minimalist in many ways, but one thing the lisps have
usually provided (always?) is data marshalling. You can write and
read recursive data structures natively. I know, there are dozens of
implementations of this out there for lua... but maybe thats a bad
thing.
That's funny, I just updated my DumpObject script, to sport a nicer
(more compact) representation of empty table. I also corrected a bug
(non-matching quotes in tostring output for functions and other special
data).

Not that anybody care, but hey! :-D
I had to write a small function to test if a table is empty. Did I miss
something more straightforward? I recall some discussions around this
point, but not the final word on the topic...
function IsTableEmpty(t)
local c = 0
for k, v in pairs(t) do c = c + 1 end
return c == 0
end
My script is still in Lua 5.0 (works fine in Lua 5.1 too).
