Why I want Concepts, sooner rather than later

We could if C++ wasn't so complicated, overwhelming, and prone to writing bad code that everyone feels compelled to replace it and going as far as starting a project like Rust to solve the issues Python or Go do for C++ with the same level of zero-cost abstractions.

Devil's Advocate: C++ may be complicated, but try comparing hello worlds in each language. Maybe Rust still isn't the holy grail either.

Rust:

  fn main() {
      println!("Hello, world!");
  }

C++:

  #include <iostream>
  
  int main() {
    std::cout << "Hello, world!";
  }

The Rust version adds a newline (hence println) while the C++ version doesn't. Either the Rust version should use `print!`, or the C++ version needs an `<< std::endl`

Adding '\n' to the string is perfectly fine, no std::endl needed (\n translates to the system-specific newline and the stream is flushed on destruction anyways).
