Refactoring code is a second nature primarily for Java developers, because Java IDEs embraced refactorings pretty early. But, why limit refactoring only to make code maintainable and understandable? What if there were refactorings that go beyond behavior preservation and make code more secure, more reliable, and run faster? That would require tools that rewrite code with surgical precision, such that the undesirable behavior of the code is fixed, while the good path behavior of the code remains intact. Being integrated with source code and development process, refactorings and program transformations not only help maintain good code, but also teach developers about how to write and appreciate good code.
