I actually can't think of any other examples off the top of my head, but the "design patterns are language features in more expressive languages" is a common idea, so I'm sure others can suggest other examples (or google). As a specific case, Python has many design patterns built into the language. Iterator pattern: generators and iter/next. Factory pattern: have class objects override __new__, callers don't need to know the details. Singleton: just use module-level functions; modules are themselves objects if you need to replace/stub/mock them. And as with any language that has first class functions/methods/callables, the command and strategy patterns mostly go away.
