C++ or Java or whatever not matching someone's aesthetics doesn't change the fact that providing an interface that accepts a Strategy or works with Commands is a design choice, not a language feature. It doesn't matter how it's implemented. The snippets of code in the GoF book aren't the point of design patterns, they're in no way canonical, and people pretending for _decades_ that they are really grinds my gears. But not as much as Clojure having no good implementation of the age old 'Readable Stacktrace' design pattern. :)
