We actually have it as a coding standard. The explicit return is required. It's obvious to some, but the time spent by a beginner or intermeddiate programmer thinking about exactly what is being returned can offset the shortcut. We have quite a lot of perl code, so we often have beginner level people looking at stuff and implicit return values really slow them down.

The performance penalty is interesting. I wasn't aware of that. Might add up if you had a sub that is called many times in your program.
