This is a fantastic new feature. I would also love a version of ‘pick’ that works on streaming data, since that doesn’t seem to be possible currently without reassembling the stream first

I just installed from Git the other day to use this feature. It’s very useful!

If you don't need to digg deep it's also possible to do:

  $ jq -n '{"a": 1, "b": {"c": 2, "d": 3}, "e": 4} | {a, e}'  
  {
    "a": 1,
    "e": 4
  }
