The idea of time-indexed outputs is that the user often wants to navigate a recording by console outputs or probe samples gathered during the playback. We can do that using replay and breakpoints.

<brrian> Given a position in a recording and a source code position and a count, the replayToIndexedStatement(PlaybackPosition, url, SourcePosition, count) command replays to the count'th execution of the statement at that position starting from the recording position. count is relative to the combination of PlaybackPosition+SourceCodeLocation.

<brrian> So, if you can tag outputs with a counter value that resets for each replay input, you can replay to any output that's tagged.
