This package is a stripped down version of Jason Gilman's Proto REPL package.
Most of the stripping down is done in service of the ability to get into a ClojureScript REPL. (Proto-REPL has features which wrap code sent to the REPL in Clojure-only functions.)
So why not contribute to the original project?
I think this package does contribute one thing, which I will try to add to the original, and that's the ability to report the correct current namespace of the REPL environment.
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
