Invalid JSON format treated as valid

[mihaipogonaru]

The parser doesn't check for the case when there is a ',' followed by nothing so strings like "[1,]" , '{"a":1,}' pass as valid JSONs

I believe this is intentional, though if it's really a problem perhaps a parser flag could be added for it?

Indeed, this is not a JSON validator. This is a JSON parser. Parsers tend to be more lenient. Why is this a problem?
