Problem:
Can you have comments in JSON?

Solution:
A discussion leading to the answer is on the Bytes IT forum.

Basically, though it's not defined in the JSON Grammar - on json.org - you can use slash-star /* ... */ comments to get most(?) javascript engines to ignore the comment text.

For example:

<script type="text/javascript">
    var nested_arrays = {
        cities: [
            ["Sydney", "Melbourne", "Canberra"]  /* Australia */
          , ["London", "Birmingham"]             /* UK */
          , ["Los Angeles", "New York"]          /* US */
        ]
    };
</script>
