Yeah, you're probably right. In my talks, I start with much simpler  
examples. *sigh* I should probably write a new, improved tutorial in  
the near future, because we've gotten a lot better at describing  
concepts in the past six months.

None of us can. As we start to get implementations of these features,  
we'll start to discover all of the interesting tricks, techniques,  
and (of course) pitfalls. But the earlier we start playing with the  
features, the better we can avoid the pitfalls :)
