C2 projects cannot compile with ClojureScript 2138

[avescodes]

Hey Kevin.

I was integrating C2 into a work project and discovered that things don't seem to work with more recent versions of ClojureScript.

For example, if you upgrade the hello-bars demo then clean target/ and public/out/ you will find the project can no longer cljsbuild.

diff --git a/hello-bars/project.clj b/hello-bars/project.clj
index 90c8b76..a982bc5 100644
--- a/hello-bars/project.clj
+++ b/hello-bars/project.clj

+  :dependencies [[org.clojure/clojure "1.5.1"]
+                 [org.clojure/clojurescript "0.0-2138"]

Result:

(Since there doesn't seem to be a 0.2.1 tag, I bumped to 0.2.2 and the line in question is dom.cljs#112)

It seems to be something to do with core.match. Can you make anything of this?

It seems as if the core.match version c2 relies on is not compatible. Bumping to 0.2.0 or 0.2.1 (the most recent) fixes compilation in the above scenario, but causes three test failures. If I get time, I'll circle around to see if I can fix them.

Doh, 0.2.3 fixes this. My bad.
