Peter Norvig notes notes that many of the patterns in the book can be implemented much more easily in Dynamic Languages than in C Plus Plus

• Mark Dominus makes a similar point. Ralph Johnson responds and Mark responds back.
• some of their patterns, implemented in Python http://www.cs.umd.edu/~yuzc/python/savikko.html
• some people, like Joe Gregorio, posit that you don't need lots of those patterns in a good language

May'2012 Ward Cunningham interview: The job was really to take C++, which was a fairly static language, and show people how to write dynamic programs in a static language. That's what most of the patterns in that book were about. And in the process, patterns extended the life of C++ by a decade, which is not what I thought would happen. What I thought would happen is people, when they learned these patterns, would look at them and say, "Wow, these patterns are hard in C++ and they're easy in Smalltalk. So if I want to think in terms of these patterns, I might as well use a language where they're easily expressed." And extend the life of Smalltalk by a decade. But the opposite happened.
