Hi Paul,

"distinguish between 1.5 and '1.5' as a key" is, IMO, one example of the advantage to have a Lua replacement for JSON.

It's what I do, I don't use JSON, I use Lua or XML to store data :)
But Lua "data" is too powerful to be read by another language if you use functions, table as keys or circular references.
(That's the reason of the first proposal.)
