I'm not saying that I don't have facilities or tools (clj-refactor) to do refactoring, just that they are, in my opinion and experience, not as good or full featured as in the mainstream static languages (and this experience seems to translate between other dynamic languages, eg, Python: I have refactoring tools, but they're not as good as what I can do in, say, Java).

Its not a huge problem, just something I miss from the static languages.
