ActionScript 3 to Ruby Examples

I have been avidly attempting to learn Ruby and to begin with, found writing out simple code comparisons for each language helped me visualise how Ruby came together better. I thought these may prove useful to some other AS3 devs looking to have a play around with Ruby so am sharing them in this blog post. I will aim to update them over time and welcome input and suggestions. There are many resources out there for learning Ruby but for a quick overview I found Lukes post and Ruby in 20 minutes were great!
