Perhaps he means something like Python's motto of "There should be one--and preferably only one--obvious way to do it." https://www.python.org/dev/peps/pep-0020/

I think all the new features are improvements, but I agree the language is getting big with many ways to do the same thing. I don't think MS will ever do a 'Python 3' and cut backwards compatibility.

I know people meme a lot about Go and "not having generics," but I really feel that a lot of the things left out of Go have benefitted it. I've never really been able to jump into a project without a lot of mental overhead. With Go, most code everywhere is written pretty idiomatically, making it easy to approach and read. I've heard similar things about C#, but my experience hasn't been as great. This is a big proble…

Yes, that's why we program in Brainf__k here: It only has the bare essentials and it's so easy to learn.

That is ugly. What he's doing is creating an anonymous function which takes no parameters and returns an int. That's what a Func is, and then he is executing that function, that's the () bit after })) He could write it nicer as: "+" => Add(), Where he defines add as int Add() => a + b; He's just doing too much inline, 99% of C# developers would not write code as he has done there. Its' the bloggers code style that is…

I agree with your conclusion, but let's keep the conversation civil.

The conversation is quite civil already.

Ah, too late to edit/delete my comment. They edited their post, perhaps in response, which is now much more considerate.
