I have limited experience with lisps, and for me a smaller language, that is easy to pick up, works well. I can finally do things in a lisp, without having to struggle with the full breadth and depth of the bigger guys (and I do not have to install e.g. jvm on my machine :). So for me it is a graceful way to work in a paradigm that I long like, but I somehow could not make my way to.
