If I understand well, you wrote/are writing a macro that parses your algol-ish language, so you can do, if your language is java, something like:

    (let ((my-java-class  
           (java public class MyClass {
                   public MyClass() {}
                   public myMethod() {System.out.println("hello");}
                  })))
          (myMethod (my-java-class)))

And it shows on the REPL:

     hello

That's quite impressive, and I can see how it opens new horizons.
