void main() {
    value employees = {"neal", "s", "stu", "j", "rich", "bob"};
    String result = ",".join(employees
                          .filter((String e) => e.longerThan(1))
                          .map((String s) => s.segment(0, 1).uppercased + s.spanFrom(1))
                          );
                          
    // using a for comprehension                      
    String result = ", ".join {
        for (i in employees)
            if (i.longerThan(1))
        		i.segment(0, 1).uppercased + i.spanFrom(1)
    };                          
}

Just stumbled upon this. A couple of suggestions:

1. As of Ceylon 1.1, the explicit type annotations in the anonymous functions are no longer required.
2. We usually write x.segment(0, 1) as x[0:1], and x.spanFrom(1) as x[1...].
