I have extensive google closure experience, but little low level clojurescript experience. Could we use the clojure library's Integer or long type. It will likely not be as fast but when you need it you need it. http://closure-library.googlecode.com/svn/docs/closure_goog_math_integer.js.html http://closure-library.googlecode.com/svn/docs/closure_goog_math_long.js.html If you can tell me if I would be wasting my time or not I will start working on a comprehensive design.
