I’ve put together a document which shows the most optimized solutions in AS3,
hope you find it useful! 
And if you find something wrong or want to add something, please tell me!
I’ve found alot by googling, but most of it is result of my own testing. You can find the “testing-code” at the bottom of the document, it’s very useful!
And sorry for having to zip it, but it was larger than 74kb.
