As a Clojurist not familiar with Dylan, that sounds awesome, but then it also just sounds like Clojure. What does Dylan add to the mix?

I'm reading their "Why Dylan?" page:

http://opendylan.org/documentation/intro-dylan/why-dylan.htm...

and I don't see anything that makes me want to go run and install it. I'm already used to dynamic, garbage-collected, infix programming languages that can be used in a functional style. Heck, JavaScript is one. Integers and strings are objects, cool, but how does that help me prototype faster or write more maintainable code?
