For example, in Python, any class can implement an __iter__ method and be used as a collection. [3] Type classes in languages like Haskell, or module signatures in ML and OCaml, are used for many of the things that protocols are used for. [clarification needed] In Rust, interfaces are called traits. [4]

In some languages, such as Python, Ruby or Smalltalk, a class is also an object; thus each class is an instance of a unique metaclass that is built into the language. [ 4 ] [ 35 ] [ 36 ] The Common Lisp Object System (CLOS) provides metaobject protocols (MOPs) to implement those classes and metaclasses.
