I do bring the issues up - but usually end up being really frustrated because I assume that these things should be obvious. A lot of the comments in this thread are forcing me to reflect though, and realize that I didnt "know" those things out of the box either - but learned them by seeing others' good code and learning from that or because someone was patient enough to walk my through my mistakes (of which I certainly still make many).
While a pull-request based system would be ideal - it's the timeline and the scope of work that has us a little bit stuck with setting up such a new process.
My key takeaways from this thread would be though that I should certainly do more of the code-reviewing & maybe even get some of the team more involved in code-reviews.
Really appreciate the tremendous feedback here and it makes me realize again why I end up spending so much time on HN - there's just so much to be learned here from some truly helpful folks!
