I have seen plenty of JSON applications abuse the "$" key namespace for comments. JSON Schema, for example, uses `$comment`[1]. So no, I don't think this is a shingle that can be uniquely hung around YAML's neck.

The Norway problem, anchors & references, infinite ways to begin a multi-line string, on the other hand, are all legitimate grievances that are somewhat unique to YAML.

Edit: And note: what makes this hack bizarre is that they chose to do it in comments, despite YAML having ample syntax for an inline dictionary or whatever else. YAML offers all kinds of exquisitely complicated ropes to hang yourself with, and they chose plain old boring comments!
