It depends on the language. The more metaprogramming is used the harder to automatically refactor. While you can do reflection/code generation even in Java, for the non-framework code almost nobody does it. That's why I feel lot safer with large codebases in Java, even though I love some dynamic languages too. I don't think they're as scalable for big programs though.
