Dissecting a Ruby Block

by Pat Shaughnessy

More than any other feature of the language, in my opinion blocks are what make using Ruby fun. But what is a block, exactly? What would I see if I could cut one open and look inside? During this talk we’ll: * Explore Ruby’s internal implementation of blocks, lambdas, procs and bindings. * Learn how closures and metaprogramming are related in Ruby internals. * Discover what metaclasses and singleton classes are and how Ruby uses them. Do you really need to know how Ruby works internally to be a good Ruby developer? Probably not. But taking a peek under the hood can help you better understand the language… and is a lot of fun!
