I would prefer to clear the confusion by calling Closure templates "soy templates", and differentiate it from the Closure compiler (for compiling javascript).
The pedant in me would like to emphasize that clojure-with-a-j predates the google product by over 2 years.
In this thread, we're talking about Google's Closure (with an S) Library. Google also makes a Closure (with an S) Compiler, but it's more of an optimizer — it "compiles" from JavaScript to optimized JavaScript.
