Re: json library

[Daniel Miller <bonsaiviking () gmail com>]

David,

I agree, the original patch was clunky; script writers shouldn't have
to know to set metatables to invoke functionality. The patch I just
attached is better: it introduces two functions, make_array and
make_object, that do the metatable-setting, while preserving any
existing metatable entries. Also, the json.typeof function will return
the JSON type that any variable would be treated as, using both the
metatable and heuristic behaviors. Finally, json.parse will now always
set the proper metatable entries.
