I've also worked with both Perl and Clojure professionally. I think Clojure code, by nature, has a higher chance at being "beautiful" or elegant, or at the very least as a close proxy, minimal. I feel that doing a lot with a little is easier in Clojure, and it makes these "beautiful" code snippets less likely to be mysterious and more likely to be understood by maintainers down the line, even sans documentation.

The non-author comment is well taken though, as I find Clojure development to have a much higher thinking-to-coding ratio, so when a solution gets translated from the author's head to code, much of the complexity can be hidden due to the conciseness and lack of verbosity. I didn't really find that to be a problem in Perl, however, with the exception of perhaps the (over/ab)use of complicated regular expressions.
