Thanks so much! It's been a really great practice. It gets them involved with the code review process from the perspective of a reviewer, which in turn leads to them writing better code on the first try (because they learn what to look for). Having to explain my choices and reconsider things I took for granted was an excellent bonus to implementing this rule, and it's made me change how I do a few things after realizing they could be done better.
