I've been circling around lisp for a couple of years. I'm starting in a month, I'll spend several hours a day. I still don't know what language I want to learn.
I was drawn to Clojure because it looked like a lisp for getting stuff done. But a few things put me off. This article puts me off more. I want to get the semantics down before I have to think about what's going on under the hood.
Clojure's lazy sequences by default are wonderful ergonomically, but it provides many ways to use strict evaluation if you want to. They aren't really a hassle either. I've been doing Clojure for the last few years and have a few grievances, but overall it's the most coherent, well thought out language I've used and I can't recommend it enough.
There is the issue of startup time with the JVM, but you can also do AOT compilation now so that really isn't a problem. Here are some other cool projects to look at if you're interested:
