I am learning design patterns once more. The book mentioned above offers the examples in java, and I read them, write them and follow the book, I really like their kind of writing. But I gave myself two other exercises besides those in the book. I would like to port those java exercises to c# and also c++(11/14), in order to get some reviews of You ( regarding all nice best practice stuff, like "there You can use lambda's, closures etc ... ), folks. So prior to flood this nice so-page with dozens of classes and interfaces, I would like to ask, whether it is ok, to do so, and if not, why or where could this be ok.
