title: How many event listeners in stage?
body: <p>With stage.numChildren I know how many objects I added to the stage, but I want to know how many addEventListener I set up.</p>
  
  <p>In doing so I can monitor the memory usage. I think the project I'm working on I can't have event listener for each one object. I think I'm going to have to take advantage of arrays and loops.</p>
  
  <p>Taking it into account I am also learning.</p>
  
  <p>Thanks in advance.</p>
