In response to [a linkpost](https://news.ycombinator.com/item?id=17358103) to [an article about how YAML isn't perfect](https://arp242.net/weblog/yaml_probably_not_so_great_after_all.html), [user jiveturkey](https://news.ycombinator.com/user?id=jiveturkey) [commented with confusion](https://news.ycombinator.com/item?id=17359727):

|
|

> `{ "firstName": "John", "lastName": "Smith", "comment": "foo", }`

> I know it isn't the same as `#comments`, but who cares really.
