I like my code laid out in a particular way, but your section on Code Layout really clamps down on a particular style. I'm not sure if it's going to be worth the effort that make absolutely sure that everyone's following exactly the same format.

A better approach is somewhere between 'I like to format my code like this' and 'I'm making changes to some existing code so I'm going to modify my coding style so the new code doesn't clash too much with the old code'

For me, a code review is more about 'is it readable and maintainable?' than 'is the one correct true style being followed?'
