Refactoring

From APIDesign

wikipedia:Code_refactoring is only useful when one has access to the overall codebase that needs to be refactored. It comes with no surprise that in the area of APIDesign where one design an API for a framework, but doesn't control its usages, that is hardly the case. As such refactoring externally visible parts of an API isn't really a good idea when one cares about BackwardCompatibility.
