|so please show me how resume would work with retry here. here is the example again:

Check the code carefully (note where "begin" is).  It's not just
replacing resume with retry.  "retry" jumps back to "begin".

|def resume_example(x)
|  begin
|    print x
|    x = x + 4
|    if x < 10
|      raise
|    end
|    print x
|  rescue
|    x = 10
|    resume  # if retry -> 51014
|  end
|  puts
|end
|resume_example(5)  # -> 510

def resume_example(x)
  print x
  x = x + 4
  begin
    if x < 10
      raise
    end
    print x
  rescue
    x = 10
    retry
  end
  puts
end
resume_example(5)  # -> 510
