Но если полиморфизм - это силища ого-го
, то у Амиги "просто библиотеки".
Кстати, уважаемый captain cobalt, раз уж вы замечены в бытности 'одептом ООП', зачитайте вот это:
Код:
Boopsi is an acronym for Basic Object Oriented Programming System for
Intuition. Using the Object Oriented Programming (OOP) model, Boopsi
represents certain Intuition entities, like Gadgets and Images, as objects.
There are many advantages to using Boopsi:
* Boopsi makes Intuition customizable and extensible. Boopsi
programmers can create new types of Boopsi objects to suit the needs
of their applications. These new types of objects are part of
Intuition and can be made public so other applications can use them.
Because applications can share the new types, application writers
don't have to waste their time duplicating each other's efforts
writing the same objects.
* New types of Boopsi objects can build on old types of Boopsi objects,
inheriting the old object's behavior. The result is that Boopsi
programmers don't have to waste their time building new objects from
scratch, they simply add to the existing object.
* OOP and Boopsi apply the concept of interchangeable parts to
Intuition programming. A Boopsi programmer can combine different
Boopsi objects (like gadgets and images) to create an entire
Graphical User Interface (GUI). The Boopsi programmer doesn't have
take the time to understand or implement the inner workings of these
objects. The Boopsi programmer only needs to know how to interact
with Boopsi objects and how to make them interact with each other.
* Boopsi objects have a consistent, command-driven interface. To the
Boopsi programmer, there is no difference between displaying a text,
border, or bitmap-based Boopsi image, even though they are rendered
quite differently. Each image object accepts a single command to
tell it to render itself.
Before reading this chapter, you should already be familiar with several
Amiga concepts. Boopsi is built on top of Intuition and uses many of its
structures. These include Intuition gadgets, images, and windows. Boopsi
also uses the tag concept to pass parameters. The "Utility Library"
chapter of this manual discusses tags. The "Utility Library" chapter also
discusses callback Hooks, which are important to the later sections of
this chapter.

Заметьте, и это на Амиге, на которой якобы 'просто библиотеки'. И не имеет никакого отношения к 'цэ-крест-крест', так как имеет место быть не в конструкциях языка, а на самом деле.
И на основе этой технологии написан MUI - очень замечательный и удобный оконный-графический амижный интерфейс.
