For Planck, I needed to build an index on the Google Closure sources. So I did so, by hacking together some regexs on deps.js.

Only recently did I learn that my "hack" was essentially already in ClojureScript. Spookily even down to the aspects of prefixing with "goog/" and memoizing the hack fn:

ClojureScript's equivalent: here

I when running (deftest test-misc...) in embedded JavaScriptCore instance
in iOS simulator, JavaScriptCore crashes with the trace below. I'm working
to isolate this to file a report with Apple and to better understand what
generated JavaScript may be causing it (perhaps we can work around).
