As a former common lisper, I don't see the point. Clojure is better in pretty much every respect and incorporates many fresh ideas (such as excellent concurrency support). Syntax is the least of CL's limitations. I didn't switch to Clojure because it was "easy" (quite the contrary).

And no, I do not miss reader macros. Perhaps more surprisingly, I don't miss CLOS at all, much as I always admired its design. It's just... Unnecessary.

What I do enjoy is STM, good performance, Java interop, ClojureScript, core.async and lots of excellent code with fresh ideas popping up all over the landscape.
