> If you want to write clean, large-scale applications, you are going to need abstractions that those languages don't have.
That's pretty much false given that nearly all large-scale applications are written in C and C++. Every operating system, every web browser, almost every type of server software, and most desktop software. You might not want to it (I prefer C# for desktop development) but it's possible. And most large-scale web software (Facebook, etc) is written in PHP. So perhaps all those developers know something that you do not.
All those features are just not necessary. They're nice to have, perhaps. You can shoot yourself in foot with them, also possible. But you can build really great and clean software without them. And you can certainly build a massive ball of mud with closures and mixins.
