Hi Jay, I really enjoyed your talk on get-bonus at RacketCon last weekend, and appreciate your sharing DOS with all of us. Also, your presentation at Strange Loop 2013 was my first introduction to delimited continuations in Racket! I have benefited from a number of your blog posts in the past, e.g. the one on an improved threading macro, and was wondering if you would consider doing a write-up on DOS?
