Description:
Closure, especially used through lambda, can be a powerful tool, which lies behind a lot of magic in Ruby (as well as other languages) Unfortunately, these tools are often misunderstood by those who didn't cut their teeth on Lisp or Haskell. This talk will show you where closure is used in innocent looking every-day ruby constructs you already use, where it appears in popular Ruby libraries and frameworks, and how to take better advantage of closure in your own code.
Comments on this Talk
The examples via IRB were a bit shallow, that is a slide would've sufficed to do those bits just fine. But I would have loved to see some more interesting live examples.
The slide that compared how multiple languages do lambda was awesome! I found myself quickly scanning them all trying to find the "best" one. I write some Actionscript professionally, and it can do lambdas as powerfully as Ruby or Javascript, but I rarely find myself doing it because the syntax is just painful and obtrusive. More depth on language-lambda comparison would be awesome.
I firmly believe this is one of the most powerful concepts in computer science, and I hope Justin refines and continues to present this talk!
