Which JSON parser with 5.3?

[Dirk Laurie <dirk.laurie@...>]

I used to like lua-cjson but it does not sit well with Lua 5.3.
Whenever a string could represent a number, it converts
it to a float, so that every integer prints with a .0 at the end.

Any recommendations for a module that works under Lua 5.3
and does not have this annoying feature?
