Characteristics:

1.it performs no object detection

2.it does not use the addeventListener / attachEvent methods

3.it keeps the correct scope (the this keyword)

4.it passes the event object correctly

5.It is entirely cross-browser (it'll probably work on IE4 and NS4)

6. And from whatI can tell it does not leak memory
