This feature is not really related to efficiency rather I think a good practice to lazy Flash development. By setting a value to null in an Object/Dictionary it can be suppressed in loops or considered not set which is better than doing constant deletes so this is always better for efficiency. Ultimately looping Dictionaries should be avoided anyway but this is a good tip if this is for some reason necessary. @Manfred I don’t think I suggested they were they are exactly the same action and did in my talk mention the use of weakReferences for Dictionary keys.

If you’re using a Dictionary try to use weak references in that case once it’s nulled the Flash garbage collector will eventually remove it for you." nulling an object inside a dictionary only sets the value to null, but does not delete the dynamic property. so these are 2 different things... delete is only used to remove properties on dynamic classes. weak references in dictionaries are often misunderstood: only the object used as key in the dict will be weak referenced not the value! this is the case when you can use an object and not a String as the key. therefore the object will not be marked as used and could be garbage collected if weak ref. is set.
