"But the JVM is just Clojure's underlying implementation. Or technically one of two." Yes, the CLR is the other half. Hmm, just trying to reassess this myself: While playing with Clojure, I found I had to use the Java libraries for basic stuff like file i/o (at least that is what all the examples pointed me to). I'd have been much happier playing with native Clojure libraries for things like that as I found the syntax became really unLisp like. I'm hoping I missed something, and that there are in fact ways to avoid the Java libraries when you want to. In which case I'd agree that "JVM is just Clojure's underlying implementation" and might in fact take another stab at Clojure.

I'm new to Clojure as well, so I don't know if there's a native way to perform normal I/O. The cleverly named article at http://copperthoughts.com/p/clojure-io-p1 http://copperthoughts.com/p/clojure-io-p1 is over a year old, so I don't know if things have changed, but it suggests that besides the slurp function (which appears as impractical from a memory standpoint as the Perl equivalent), you really do need to dip into Java for I/O. Assuming it's just a matter of time before I/O and all other common tasks in Clojure are done in native Clojure, it really seems like a contender for the pg "hundred year language." It has lots of default macro shortcuts for common tasks and really seems to prefer abstracting away redundancy to following tradition. It even uses the Arc-style let macro instead of the paren-happy one found in Scheme and CL. It also makes concurrency almost as simple as pg's "Bring Back Moore's Law" startup idea. And it's also well suited to web applications. The more I think about, the more it really does seem to be the Arc that's already here.

While it is not a totally Clojure native IO lib, there is clojure.java.io http://richhickey.github.com/clojure/clojure.java.io-api.html http://richhickey.github.com/clojure/clojure.java.io-api.htm... which gives you more LISP like syntax when dealing with common IO functions. That being said, it is just wrapping much of the same stuff you would do with the Java libs directly.
