We were looking at how to convert Middleman web content, basically all Ruby and ERB, to be Clojure-based. Of the tools we surveyed, nothing looked suitable for thee task, so we decided to make something that is. After some effort, the system has reached a point where it seems reasonable enough to share as a library. We call it Ash Ra Template, or ART 
If you are looking for more programatic flexibility than other Clojure templating systems, give Ash Ra Template a try and let us know what you think!
In terms of a roadmap, the README.md lists some improvements necessary before version 1.0 can reasonably be declared.
Cheers
