Code reviews (and standards) can also prevent cleverness (i.e.: actual code golfing in producton code). However, if the reviewer is not more experienced in the language, low performing or unnecessary constructs can still slip. I also think that there must a an automatic tool (like Perl::Critic) in the process. Btw, if you are implementing coding standards into the process, then it must be applied backwards on old code too IMHO. Lets say; if you forbid tabs, remove tab indentation from older code if it is still maintained. And column width is usually missed. I hate to see 500 chars on a code line (nope, word wrapping in an editor does not solve this shit).
