Where's the best place to handle removing class event listeners? partRemoved is great for cleaning up after partAdded...is there something comparable for an entire class?
It is often wise to remove some listeners when REMOVED_FROM_STAGE, but there
is no deconstructor or other code that runs just before an object gets GC'd.
You have to decide what the likelihood that an object will be re-added to
the stage and whether it is efficient to remove and re-add listeners that
Sometimes we'll require that you call a release() or unload() API and
sometimes we'll also use weak reference listeners.
Thanks. I've seen removedFromStage used a fair amount, but wasn't sure if it was ideal or not.
