After reading through it quickly, I agree that this would provide 
interresting extensions, as well.
Especially, i like the idea of presenting different selectors depending 
on the number of times an event was triggered, and the way it is 
expressed is really simple and functionnal.

To take a simple animation example, it would also come in handy many 
times, used with the onevent syntax:
   div:onclick(2n+1) {onclick: "animOpen(this)";}
   div:onclick(2n) {onclick: "animClose(this)";}

Instead of having to keep track each time in the script of wich 
animation to use for each element (of course that is just a very basic 
example to show how the two syntaxes would mix together).
