I'm interested in hearing from anyone who has experimented with, or implemented play/production systems using strategies/techniques/concepts from the book.<p>Which techniques did you use? Which did you not?<p>How was the development experience different?<p>Did you find them useful?<p>What took the longest to wrap your head around/get used to?<p>How "total" was your use of techniques throughout development: were you writing a bunch of combinators from square one, or did you pick and choose specific instances to use ideas from the book?<p>Would appreciate indication if the project in question was a personal side-project, or a production system with other developers involved.
Any other thoughts and comments are welcome as well.
