Thank you all for your kind words, both public and private. You know the line about standing on shoulders, but it turns out that if the shoulders you stand on are sufficiently tall, mere crouching is sufficient. Those shoulders belong not only to Matthias but also especially to Robby Findler, Cormac Flanagan, and Matthew Flatt, each of whom is smarter than me and whom I continue to look up to. And (rest PLT), notably John Clements and Eli Barzilay, has also kept me on my toes.
At Brown I've been fortunate to have outstanding PhD students -- Paul Graunke, Greg Cooper, Jay McCarthy, Arjun Guha, Joe Politz -- as well as several undergrads, post-docs, and collaborators (Kathi Fisler and Dan Dougherty) who've similarly constantly been several steps ahead of me and been kind enough to bring me along.
