I've spent more time in Ruby and Java than other languages. My background is leaking through. :) Feel free to post any other tools to the comments on the article. Re: DSLs... I don't think the DSL specs always stay in front of the customer (they sometimes do), but they're a valuable tool. Whether it's a developer, a technical customer, or a non technical customer, you've provided a much simpler way to show what the system does. That's a huge win. I also find that developers who spend time in DSLs tend to write much cleaner code. Once you get used that level of abstraction, you use it in other places.
