title: How to delete arbitrary objects in repeated field? (protobuf)
body: <p>I have some entries in the repeated field in my proto. Now I want delete some of them. How can I accomplish this? There is a function to delete the last element, but I want to delete arbitrary elements. I cant just swap them because the order is important.</p>
  
  <p>I could swap with next until end, but isn't there a nicer solution?</p>
