Well, this is interesting. I haven't been able to reproduce this without Boot-cljs completely, but I can reproduce this with Cljs by manually providing extern with single line: var COMPILED;. For some reason, inferred extern with Boot-cljs includes this line, but not when calling compiler directly.
