Looking a bit further, I see that in all places where a `CheckablePullRequest` is created, we already have a list of comments, so I think an even better solution here is to add a `comments` field and supply it to the constructor.

Was there a reason you didn't add the comments as a field in `CheckablePullRequest`? I think that would make more sense as the `PullRequest` already is a field.
