Review for NeurIPS paper: Implicit Distributional Reinforcement Learning

There was much discussion around the relationship with Tessler et al., which at first seemed quite close. I reached out to the authors for a clarification, as Reviewer 3 had omitted requesting it in their review. After this clarification, the reviewers decided that the work was indeed sufficiently novel and interesting. For the record, the reviewers unanimously appreciated receiving the author clarification (as, I can imagine, the authors appreciated sending it). However, that clarification itself was quite long (5 paragraphs).
