Perl, Python, and Ruby are successively closer approximations of Common Lisp.

I admire the ideas behind Clojure because it makes a different set of design decisions from Common Lisp. This seems to have even gotten the attention of Common Lisp developers, and those guys are pretty hard to impress.

The focus on immutability, literals for data structures other than lists that share a common "seq" interface, first class functions and closures, multi-methods without OO, lazy sequences, and full fledged macros hit an interesting sweet spot that is not touched by any other language I know. Mr. Hickey has managed to put all of those things together in a way that strengthen, reinforce, and complement one another. That is an impressive feat of language design.

My point is that Clojure is not "just" popular. By making unique decisions about the semantics of the language, and not just improving the syntax over the semantics of an existing language, Clojure may very well be one of those languages whose ideas remain influential long after it stops being popular.

(I'm curious, does Arc innovate in terms of its semantics being significantly different than its predecessors? It seems to have the goal of taking existing Lisp paradigms and making it possible to express them more succinctly. But I might be missing something important.)

So, even by the criteria you put forth, Clojure might be a language worth watching.

Clojure has already taken many things from Arc (there is also 'prn !)
