title: How do you add a comment to a json IAM policy?
body: <p>IAM policy are complicated beasts.  It would be nice to add a comment when crafting them.  For example,</p>
  
  <pre><code>{
    "Version": "2012-10-17",
    "Statement": [
      {
        "Sid": "Stmt1422979261000",
        "Effect": "Allow",
        "Action": [
          "route53:ListHostedZones",
        ],
        "Comment": "Foo"
        # or Bar
        "Resource": [
          "*"
        ]
      }
    ]
  }
  </code></pre>
  
  <p>Neither of these work.  Does there exist a way to add comments to these policies?</p>
