I am thinking along the same lines. If something is not "policed", then it won't happen in the long run as interest shifts. Includes programming practices, testing coverage and the usual stuff. And more effective to automate such things and spend code reviews on interesting issues, not "punctuation".

I wonder if anyone has examples for or against of running such checks against your codebase? I can imagine some horror stories of how those tools would slow down all useful work. But some success stories? I guess I have to try on myself first :)
