How do I fetch comments in version 3 of the YouTube API?

Question

How do I fetch comments for a video in version 3 of the YouTube API? I've been trying youtube.activities.list and youtube.videos.list and most other methods available in the Google API Explorer. Am I missing something here?

(youtube.activities.list seems to be the proper call, but that only returns my own uploads and playlist items.)

Update: Comments feature is now available in Data API v3. http://youtube-eng.blogspot.com/2015/04/manage-comments-with-youtube-data-api-v3.html
