I read the JsonParser features and it is great that there are relaxed features available. I was reading JSON5 and HJSON and they have some interesting features.

Full support for JSON5 would be great. I especially miss:

Multiline strings:

lineBreaks: "Look, Mom! \
No \\n's!",

Trailing comma:

{
"field": 1,
}

It would be great if you could consider an addition of these features. I have not found such request between issues. Thank you
