I wish there was someone around who has had a chance to look at some of his code. Something I've noticed from years of doing code reviews and consulting is that people who are that verbose in their writing tend to be very verbose in their coding. I wonder if Steve generates massive classes when they could be done much smaller.
Again, it's totally unfounded, I'm just speaking from anecdotal evidence.
He has actually talked about your question. Over the years he has come to believe that size is the enemy of code and verbosity is the portrait of n00b.
