If *your* writing is not a failure time will tell. * This article seeks to improve on the situation by: - providing practical use cases - giving a clear mental model of how it works - showing the tradecraft for getting it to work every time - concrete advice for building classes that use super() - solutions to common issues - favoring real examples over abstract ABCD diamond diagrams<http://en.wikipedia.org/wiki/Diamond_problem> . * These strikes me as notes by the author for the author. You could easily extract the gist of the above points and convert them into a sentence or two. Overall, take everything up to the end of the last bullet point and convert it into a 2-3 sentence intro paragraph. -- Brian Mingus Graduate student Computational Cognitive Neuroscience Lab University of Colorado at Boulder
