I don't know why there are not more code analysis and refactoring engines for dynamic languages. Sure, it takes more guessing on part of the tool, but I see no reason why they can't identify and help with a large portion of such tasks. It shouldn't be an all-or-nothing thing. Sure, the more "meta" your programming, the harder it is to automate analysis, but only a portion of an application typically requires high meta.

Because the refactorings are generally impossible. At best the automated tool could tell you everywhere it thinks a change might be necessary, but has to ask you want you want to do there. And it would likely greatly over or underestimate the number of changes needed. It's rather akin to saying "why can't the system implement my functions for based on their signatures?"
