Hey, this sounds interesting. I just tried it on my project but it seems to be missing several keywords in the constants_table.js.
Dumb example: the code tries to use cljs.core.constant$keyword$1064 , which does not exist. Will try to investigate, just a heads up. /thomas On Wednesday, August 28, 2013 3:29:26 PM UTC+2, David Nolen wrote: > > ClojureScript has long represented symbols and keywords as JavaScript > Strings as a performance optimization around hash maps.
