My preference is to have all of the code functions together -- that is, not alternating with POD. POD lives in a separate file, since that's one of the options.

I am known as a developer who includes lengthy comments, so there is documentation in my code. I just prefer to keep user information somewhere else -- that's not useful information for me, so I don't want to see it. And I'm aware that some IDEs allow you to hide POD -- that's wonderful, but I'll stick with plain vanilla vim. It's always available, and behaves consistently pretty much anywhere.
