Delegation (programming)
In object-oriented programming, there are two related notions of delegation.* Most commonly, it refers to a programming language feature making use of the method lookup rules for dispatching so-called self-calls as defined by Lieberman in his 1986 paper "Using Prototypical Objects to Implement...
. Object systems based on inheritance only allow inheriting from classes

In object-oriented programming, a class is a construct that is used as a blueprint to create instances of itself – referred to as class instances, class objects, instance objects or simply objects. A class defines constituent members which enable these class instances to have state and behavior...

Snit is intended to help build applications out of the code at hand. Thus, Snit is designed to be able to incorporate and build on any object, whether a hand-coded object, a Tk
