I'm not entirely certain these are the same thing. They serve a similar purpose: pull common behavior out to a common piece of code. But a critical part of what they do in TurboGears is to *configure* that common behavior. Most methods will have different templates formatting the output. They'll have different sets of validators. Different authentication requirements. So, functionally, the TurboGears decorators pull common behavior out. But, just as important, they configure how that method should interface with the web. As much as possible, this lets the method look like a fairly standard piece of Python code. Kevin
