I realize that I may have wrote this post a bit prematurely. I 
only looked at the code in your slides before writing this and 
didn't realize that you had mentioned the same point I made here 
in your live talk (about equal elements). So I may have come off 
a bit condescending and that wasn't my intention. Great talk 
though, interesting topic and always entertaining to watch you 
speak.
