How to declare functions which never returns. Those functions are useful when function is acts as termination so it exits whole application or always throws something.

  • In C++ is [[noreturn]] attribute.
  • In Swift is Never return type.
  • In Rust is ! return type.

I don't think this is important now, but for the future version of the language. Mainly it helps the compiler to optimize code.
