      I'm querying the oplog.rs collection and I would like to exclude the o.$set field from the results. The 'o.$set': 0 projection gives an error:

      "Cannot exclude array elements with the positional operator."

      There doesn't seem to be other ways to exclude it. Am I wrong? Is it possible?
