Will Groovy help against me mistyping "adress"?

I guess neither solutions are ideal, and both have pros and cons! I'd still favour Groovy, obviously (I'm biased though), as you can go much further in terms of DSLs as you could do in Java.

Groovy is definitely more elegant, but it's a tradeoff, not a clear win. I must admit, that the lack of finish() method is nice. I could get rid of it with closures, but the anonymous classes just look too ugly at the moment to consider.

Comment from my co-worker: "Builder pattern for President". Good stuff. The day when you posted this I implemented a similar ad-hoc DSL. Comment from my co-worker: “Builder pattern for President”.
