RubyConf 2013 was a fantastic experience and I was fortunate enough to give a presentation about learning from the tools in the Standard Library. The presentation was recorded and will be online soon.

While the slides alone don't reveal the value from my presentation, I encouraged the audience to read the ruby source and discover what the standard library has to offer. We looked at how delegate.rb and forwardable.rb can help solve problems and how they are implemented. There's plenty of tricks to pick up in there.

I had a great time having a chat on Ruby5 too.
