DSLs: Introducing Slang

Did you ever ask for a more compact way to express something in your favorite programming language? Say hello to DSL (Domain Specific Language). A DSL is a slang, a compact way to say what you want.

And when these guys do it, there's no reason for us not to.

Here is an artical on Java World which gives some nice examples how to create a slang in Java and in Groovy. Pizza-lovers of the world, eat your heart out.
