This is just a plain old Python class that will work back to probably Python 1.4 or so. If you want to write a version that has just the right amount of magic, you are free to. That said, I *DID* give it the wrong name in my first post of this thread. GreedyAccess is more accurate, and a NoneCoalesce class would behave somewhat differently. In my opinion, the need at issue is worthwhile, but niche. Using a special class to deal with such a case is absolutely the right level of abstraction. Syntax is not! So sure, figure out how to tweak the API to be most useful, find a better name for the class, etc. I wouldn't think it terrible if a class like this (but better) found a home in the standard library, but it doesn't deserve more prominence than that. Not even builtins, and *definitely* not syntax. -- Keeping medicines from the bloodstreams of the sick; food from the bellies of the hungry; books from the hands of the uneducated; technology from the underdeveloped; and putting advocates of freedom in prisons. Intellectual property is to the 21st century what the slave trade was to the 16th.
