C as a Portable Intermediate Language

I think the CoffeeScript approach is the way to go: syntactic sugar that generates human readable code. I'd be happy to have an elegant language that would compile to C++ simply adding some DRYness and elegance (for example not having to write headers), but without trading it for performance/portability (for example without abstracting pointers or new/delete). I would happily use a subset of C++ if required.

This in C++:

    // in file MyClass.h //////////////

      class MyClass: public ParentClass
      {
  
      public:

        int myInt, myInt2;
        float myFloat;
        Arr *myArr;

        MyClass() { }

        MyClass();
        void doStuff();

      };

    //in file MyClass.cpp  //////////////

      #include "MyClass.h"
      MyClass::MyClass()
      {
        self->doStuff();
        int poop = 321654987;
        myInt = 112233 * poop;
        {
          // new scope here
        }
      }

      void MyClass::doStuff()
      {
        int myNum = 123;
        poop *= myNum;
      }

    class MyClass < ParentClass
  
      int myInt, myInt2
      float myFloat
      Arr *myArr
  
      void initialize(args)
        self.doStuff()
        int poop = 321654987
        myInt = 112233 * poop
          // new scope here
      
      void doStuff()
        myNum := 123;
        poop *= myNum;
