If we're going by the traditional idea of "bytecode interpreter" or "threaded interpreter", clojure is emphatically not one of them. It JIT compiles the lisp to JVM bytecode; the equivalent in Pixie would be JIT compiling to native code. IIRC with RPython/pypy the two techniques are interleaved, but most users I've seen opt for some JIT optimization.
