That "Stop Coding!" blog is looks like it'll be a REALLY good resource. Thanks for that, henke.
A while ago I had posted a thread intended to go here on Closures in AS3. I didn't post it here, but it's here:
Closures in Actionscript 3
At the time of posting, I thought they were more of a 'gee whiz' sort of thing, but I've actually found them very useful several times since then. They might take a minute to wrap your head around and may look a little weird at first, they can actually make your code look and read much more simply when appropraitely placed.
I'll probably write another quick one in a little while.
