I agree. The most important feature of a high level programming language is first class closures with lexical scoping. Almost every design pattern, including the IOC in the original article, can be implemented with them (along with a few other core data structures and primitive operators). By contrast, there are many patterns that are very difficult to implement by hand in c because of the lack of first class closure support (c++ of course is a bit better since it has lambdas, but then you have to opt in to everything else in c++).
