Hi Frank,
That is pretty much exactly as I wanted. The only problem is that you are
calling a private fn and therefore the code is susceptible to change. I
think this should be looked into more and become officially supported. This
is a great hook that opens up the door to a more interactive development
experience for clojurescript.
