Many programming languages embed design patterns right into the language. I'm looking for the most obvious examples, like Python decorators (Decorator?) or C# events (Observer). Can you give me some more?

I've also beein intrigued by this very question and even asked a similar quesiton once: Design pattern as (missing) language feature
Sure, there are some more patterns that simply vanish in other languages.
- Singleton: in Scala, you can define singleton with the
objectkeyword. - Factory: in Smalltalk, classes are first-class and serve de facto as factories for their instances, no need of additional boilerplate.
- Visitor: in Clojure, you have multimethods to help with this problem.
- etc.
Most information about this topic is annectodical. You can check the links in my question. That would be nice to have a more complete coverage of this topic, sadly I've never found one.
