As a corollary, I can tell a code review session has reached its end when we start debating coding style, which I find happens about 2 minutes after we agree to talk about coding style at all. I've never found the intricacies of variable naming helpful, though I've participating in a number of discussions on the subject. Code style guidelines are just that: guidelines. Being able to work in a group with a broad range of coders (from inexperienced to hyper-genius) is a highly useful skill for a coder. Being able to communicate about the project to management, customers, and online is an even greater skill.
