I did not try Clojure so I cannot comment on how well implemented the features you quote are, when compared to CL. All I can say is that CL also provides much of the same functionality with its standard, cl-async, lparallel, parenscript, while (im)mutability is a matter of preference (IMO correct decision by CL) rather than dominance. The way I see it, is that CL is superior (opinion) due to reader macros and native compilation, rather than bytecode JVM.
