You know, B::Deparse makes some mostly good guesses about how to reconstitute compiled perl as source code but I don't generally take its output as gospel. Use better things like B::Concise, B::Terse, B::Debug. I highly prefer viewing Concise over most other versions when looking to see how perl compiles something. You get enough information to understand your program and you have none of the reconstitution ambiguity inherent in B::Deparse.
