Tell me which is simpler:
Reader.read("{:foo 1 :bar " + x + "}");
or
Var keyword = RT.var("clojure.core", "keyword");
Var hashMap = RT.var("clojure.core", "hash-map");
hashMap.invoke(keyword.invoke("foo"), 1, keyword.invoke("bar"), x);
Nobody suggested using the reader in the cases where it is actually
more compact to express using stuff like the above, by the way.
