AmbientTalk’s object instantiation protocol closely corresponds to class instantiation in class-based languages, except that the new object is a clone of an existing object, rather than an empty object allocated from a class. We further explain the semantics of object cloning in subsection [[objects#Delegation_and_cloning|Delegation and cloning]].
