The refactoring is a distinct step performed BEFORE the enhancement in order to enable the enhancement. Of course, eliminating duplication is a primary motivation. Another motivation is altering the existing interfaces and implementation to make the enhancement EASY. I do this on a regular basis, and I find it to be indispensable. As Martin says, you should alternate putting on your "refactoring" and your "enhancing" hats, never mix them (do both simultaneously).

I like your idea of using stubs - I'll have to try that out. Thanks for the kind words in your article, Chris, about my site. I like your idea of using stubs – I’ll have to try that out.

I'm stubbing a response to this article with my preferred technique of getting out of the "Reuse Trap" on my blog. I'll try to remember to provide a link once I'm finished. Good post.
