Lambda and Closure: Horrors of the Computer Science Mythos
by Justin Love
Lambdas and the related property of closure can be powerful tools, and they lie 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. The talk will cover the most common syntax, several ways of looking the concepts, and common patterns of use with several examples drawn from popular ruby libraries. Visit http://github.com/Jus... (http://github.com/JustinLove/ruby_closure_examples) for examples and to get a head start on this talk.
