Oops, I accidentally posted this before I finished typing it. I guess most
of what I was trying to convey made it through.
The second ns form I posted is my suggested approach. It requires no
modifications to the Clojure language, and would be pretty simple to
implement in the ClojureScript compiler. I'd be more than happy to
implement such support if people thought it was desirable.
