On JSON parsers

[Hisham <h@...>]

An interesting work on checking the compliance and compatibility of
JSON parsers:

http://seriot.ch/parsing_json.html

The author wrote a test suite comparing 34 different JSON parser
implementations in several languages (there are two Lua
implementations there, Jeffrey Friedl's and lua-dkjson) and found out
that there are no two alike.

This reminded me of the complaint given a few times about the Lua
module ecosystem having "too many JSON parsers" or something like
that, so I thought it would be interesting to share it here. :)
