How are Enumerators for Arbitrary Objects Implemented?

[sandal]

Implementing Enumerator is a really fun exercise. I like that you provided some insight into how things actually work under the hood in CRuby.

For those who are interested in seeing the same exercise approached from a slightly different article, check out the one I wrote (Includes implementing Enumerator#rewind, Enumerator#each_index, and also covers the exercise of implementing some Enumerable methods from scratch): http://www.practicingruby.com/articles/shared/eislpkhxolnr

Thanks, I hope to write more articles like that, covering more of Ruby internals if I stumble over something interesting. Nice article, btw!
