For an example of the "recommended" way to get the ordering of your class attributes: http://stackoverflow.com/questions/3288107/how-can-i-get-fields-in-an-origin...
This is already possible with the __prepare__ magic method. http://docs.python.org/3.4/reference/datamodel.html#preparing-the-class-name...
It seems to me that the "right thing" for python to do when given an ordered list of key=value pairs in a function call or class definition, is to retain the order. So what's an acceptable level of performance regression for the sake of doing things the "right way" here?
Or, rather, what is the benefit of doing things "the right way"? There are incredibly few cases for relying on the order of key=value pairs in function calls. Regards Antoine.
