In Java, if I want to delegate the foo and bar methods to my component a, I have to say something like:

public int foo(int x) {
return a.foo(x);
}

public void bar() {
a.bar();
}

Is there a programming language that natively supports delegation? I'm imagining something like:

delegate a: foo, bar;

This would make it much easier to choose composition over inheritance.

I'm using https://refactoring.guru/design-patterns in my software development course. It's pretty good and, in the words of the late Portland TV pitchman Tom Peterson, "free is a very good price".

I have two concerns:

Rather than just working through the original Gang of Four list, would it be more meaningful to talk about ideas that come up in several of these patterns, like interfaces, delegation, and composition?

How do design patterns change when working in a language like Python rather than C++ or Java? There might be better solutions to some of these problems in a world with duck typing, higher-order functions, optional named arguments, etc.

How come "make-work" is bad but "creating jobs" is good?

What is more unpleasant?
