What's so wrong about classical inheritance, and how it died away while being well-supported in most popular programming languages of today (Python, C++, Java, C#, TS, Swift)?
Inheritance has its uses, but is easily overused.
In a sense, it’s like global variables. About every complex program [1] has a few of them, so languages have to support them, but you shouldn’t have too many of them, and people tend to say “don’t use globals”.
[1] some languages such as classical Java made it technically impossible to create them, but you can effectively create one with
If you’re opposed to that, you’ll end up with making that field non-static and introducing a singleton instance of “Foo”, again effectively creating a global.In some Java circles, programmers will also wrap access to that field in getters and setters, and then use annotations to generate those methods, but that doesn’t make such fields non-global.
