Unable to encode 'sparse array's

[rxi]

This becomes a problem in scenarios where you have a table as such:

{ [1] = true, [1000000] = true }

If you want to encode a sparse array you should either manually replace the missing values with false, convert the keys to string before encoding, or use a format other than JSON.

Hi @rxi,
Can you please clarify why such structure cannot be converted into JSON {"1": true, "1000000": true}?

@makarov-roman See #12

I see your point, but sometimes you don't care if [1] became "1" (exactly my case). I've managed to export data with https://github.com/harningt/luajson which treat numbers this way.
It would be nice to have on option for this under flag. convertNumberKeysToStrings or something.

I like that this failed. I had an "array" indexed at zero. Very happy that I saw a failure rather than JSON going out in the form { "0" : val1, "1" : val2 }.
