It&#x27;s mature (since 1996); runs on the JVM; compatible with Scheme standards (basically full R7RS except for continuations); great Java&#x2F;JVM interop; trivial and flexible deployment (just a jar, unlike Clojure which assumes its own eco-system); extremely fast start-up (easily beats ABCL and Clojure); good compile-time and run-type error-reporting; and best-of-class runtime speed (comparable to Java&#x2F;Scala with appropriate use of optional type specifiers).
