repl). Try it, it's good! https://github.com/hyperfiddle/rcf/

For ultra-dynamic web applications, Electric Clojure is a *reactive and

Datomic allows clojure.core fns to be embedded inside datalog queries,
except eval (http://docs.datomic.com/query.html)

deployment/build scripts. We've been incubating it for about two years and
been through a
