You don't need Shen features in Clojure because the Shen team aims to provide a compiler for KLambda which is a very small subset of Lisp. It should be no problem to implement KLambda in Clojure.
"Much of the work necessary for converting to Clojure or Python (Or any other non-tco language) is being done as a pass over KLambda right now in my JS port. Once this is finalized, it should be relatively easy to port the transformed KLambda code to any architecture that supports exceptions or labels."
