Brought the problem down the bottom.
Don't know, what standard tells about this.
If a port cannot be recognized, thats ok, but I would expect to get an error message.
```
>var x = {port:C5};
={ "port": C5 }
>var j = JSON.stringify(x);
="{\"port\":C5}"
>var y = JSON.parse(j);
=undefined
```

Yes, that's odd - it seems like JSON.parse should really produce an exception. Could you file a bug for it on GitHub?

The whole parsing thing is annoying. It did work, and then someone raised a bug because it worked when it should have failed, and that could have been a security bug - maybe. So I had to disable it :(

So if you care about stuff like that, now you have to use eval - but if you do that then you need to be sure you trust your source of data :)

Is this because C5 has special meaning? Would it work with an int or string?

Yes, ints and strings are fine. If it was being spec compliant, JSON.stringify should really replace it with undefined I believe.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
