Flex Garbage collection and styles

I read a really great post in my endless search for better garbage collection in AIR and Flex. Bernd Bindreiter of firstrow RIA posted a 5-part series on garbage collection and one of them involves removing skins from Button controls in order to have them garbage collected properly. In his post he removes each individual skin from the button using something like:

myButton.setStyle("overSkin", null);
myButton.setStyle("upSkin", null);
myButton.setStyle("downSkin", null);

What I wondered was if I could do the same thing by just setting the styleName to null:

myButton.sytleName = null;

This does work for skins, but as Bernd’s comments point out, other styles such as “color, fontSize, paddingTop” don’t create memory leaks, so this method only works with skins. However, setting the styleName to null is also an effective way for marking the object ready to be garbage collected. I recommend reading the rest of his posts about garbage collection techniques. I am always searching for the holy grail of garbage collection and his posts were very insightful.
