Then perhaps this is a point where we talk to Guido and ask him to bend Python a little to allow a more consistent story for Python-on-.NET. And remember that it's not just methods and classes. Members are also valid attribute targets. We could come up with a different decorator altogether without breaking Python. "//@", perhaps? (Easily uncommented in the event that Python decorators on non-classes are approved.) ----- Keith J. Farmer // [EMAIL PROTECTED]

True, Python 2.4 doesn't support them on classes, only functions. I think consistency should be sought here. After reading PEP 318 (http://www.python.org/dev/peps/pep-0318/) a little closer, I noticed that there *are* some examples of using decorators on classes. (See examples 2 and 5 at the end of the PEP). While not included in 2.4, I could not find if it has been ruled out as a later enhancement. Note that there may be a potential problem using decorator syntax for attributes. In CPython, a decorator is merely a syntactical shortcut for applying a function to a function definition. It could be said that, in IronPython, the attribute is being applied to a function. To me, this seems kind of confused, as the attribute descriptor now becomes a special case descriptor for the interpreter to have to handle because the descriptor is not being called with the function/class definition as an argument. Instead, the attributes must be compiled into the generated code. It is probably not that large of a deal, though. (Just playing devil's advocate here). Despite this, I still like the decorator syntax. -Nathan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dino Viehland Sent: Monday, March 27, 2006 11:45 PM To: Discussion of IronPython Subject: Re: [IronPython] .NET Attributes I like this too... It's interesting that while the syntax isn't exactly the same for giving both classes & functions attributes they are both getting that information in the same way. I was previously worried about the differences between classes & functions but I think this brings it all together. ------------------------------------------------------------------------ ------------------------- ------------------------- CONFIDENTIALITY AND SECURITY NOTICE This e-mail contains information that may be confidential and proprietary.
