# Objects
|
|
|
|
## Overview
|
|
|
|
In Scheme, as in other Lisp dialects, "everything is an object". But
|
|
Scheme is not "object-oriented" in the sense of classes and methods.
|
|
|
|
Various Scheme implementations have bolted an object system on top of
|
|
standard Scheme. Most of these are variants of the Common Lisp Object
|
|
System (CLOS) which evolved from an older Lisp Machine object system
|
|
called Flavors. The Kawa and IronScheme implementations have Java and
|
|
C# style object systems, respectively.

* Ad-hoc polymorphism (generic functions and methods).

* Single inheritance and mono-dispatch.

* Introspection.
