title: Conceptually looping and breaking in a sequence diagram
body: <p>What I am doing is get the marks of each and every student for a course, here I have created an explicit lifeline for students (the student list in the course object) and then even added a "get(indexValue)" method to show that it is iterated over to get each student.</p>
  
  <p>The issue is that I wish to be a bit less detailed and more conceptual, how should I structure my diagram in order to show that there is looping over all the students in the course without explicitly defining it by using a studeentList lifeline and using a "get(indexValue)" method as seen in lists in Java.</p>
  
  <p>Additionally is this representation correct if having a more detailed diagram was the objective as well. Also regarding breaking a loop I have used a return statement in a loop (as seen in programming languages), I have also seen some versions on the internet use "break" fragments to highlight this, is there a need to be specific for that either</p>
