I honestly believe that mandated style guides for coding are a waste of time. It's so easy to just run all code through perltidy (or the like) and automatically format every line up to a common standard. No reason to chastise coders for their evil non standard ways, or hoist meetings and style reviews on an otherwise productive day. Just let programmers do their thing and then perltidy it before sharing.
If the world spent more time using pertidy and less time endlessly arguing coding standards, we'd all get more work done.
