Weakreference question

Okay, so after reading Skinner’s article http://www.gskinner.com/blog/archives/2006/08/as3_resource_ma_2.html concerning weak references, I am still a bit confused.

If I use removeEventListener, is it the same thing?

And since the listeners are removed automatically… does this mean if I have a Mouse click event listener and I weakly reference it that it could be removed by the GC before the user even clicks? Could someone give me an example of when it would work?

Thanks
