I just gave attr another look -- I bounced off it before because of the cutesy naming. It's a matter of taste, but I thought it was unlikely that a library that made such a grating decision would be fun to use. My second impression is that I've got to give attr points for clarity: the implementation is short and to the point, considering how much it monkeys around with Python's classes. I can see why you'd want to use it for an API, because it won't endow an object with unwanted Sequence methods. Not an issue in my current job, but your point is well taken.
