Several issues

[lazytyper]

I've been testing jsonic for a few minutes and discovered several issues:

1. JSON file can contain just a number or string:

JSON.parse('0')
// -> 0
JSON.parse('"a string"')
// -> 'a string'

jsonic cannot parse this, but should be compatible to JSON.

2. Hexadecimal number support ?

{ 0x12: 0x14 }
// -> { '18': 20 }
jsonic('{0x12:0x14}')
{ '0x12': '0x14' }

The result is not what I expected (same result as in JS). Hexadecimal numbers could be supported.
And invalid numbers like 0g12 could cause a parse error.

3. Strings without quote

I don't really like that way string don't require quotes. It can confuse and it's not much work to add two quotes.

Example:

var name = 'John Doe';
var o = { name: name }

I don't need to tell what the result of js and jsonic is.
And { name: John Joe } is not even valid JS.
Better: disable that by default, and require quotes.
If the programmer badly wants the short syntax, it could be turned on optionally.

I already found a similar parser which seems to be perfect:
It parses "just a number/string" correctly, supports hex codes and it doesn't support exotic syntaxes.

@lazytyper actually in the middle of a big rewrite to address those issues! :)
Which parser did you choose?

[lazytyper]

It's json5 (www.json5.org).
