That would exactly be my point, too: I want to write idiomatic Clojure and have the underlying runtime make it perform; that's what I get with Java. I don't want to twist the compiler's arm into producing the bytecode that I can get from straightforward Java code.
Incidentally, it happens that the piece of code that I have mentioned is also about heavy string matching.
