A great question. Honestly it's a very natural fit for me, so I'm probably not very well qualified to answer.

There can be a lot of code repetition. To me, that's not a bad thing. I've seen people to themselves in knots trying to DRY some common code, just to later have to undo it all because a requirement changed for only one of the code paths. And, as I said, I like my procedures to read like use cases.

I'll see if I can think of anything else...
