Guy Steele on learning programming languages
About an year ago, while casually browsing, I wandered into Oracle Labs website and found Guy Steele’s page. If you don’t know who Guy Steele is, perhaps watching this video is a good start. In summary, Guy Steele was a student of Prof. Gerald Sussman and they together invented the legendary language SCHEME. I am a big fan of Scheme and its simplicity. I think I have watched almost every Guy Steele lecture videos freely available out there. In particular, I am a big fan of the Dan Friedman 60th birthday lecture, “Growing a language” lecture and so on. Youtube is your friend.
Coming back to the topic, I couldn’t resist emailing him and just say that I am a big fan of Scheme. With his permission, I am reproducing the email conversation we had and his great advice.

The "Lambda, the Ultimate" papers have held up pretty well over the years, I think, but there is much, much more. I recommend any paper that has Phil Wadler, Simon Peyton Jones, or Charles Leiserson as a co-author. Also, study more programming languages. Any will do, but there seem to be a lot of good ideas nowadays in Haskell, Clojure, Python, and Scala. You are much better off, I think, knowing three good programming languages than one really great one. And read code in each of these languages, maybe the code for their standard libraries as well as an application. Good luck! Yours, Guy Steele
