Hello everybody,

I ran across a nice feature the Firefox and Webkit developers are currently
working on: the possibility of mapping the javascript source code executed
by the VM and another file of source code, for example written in
clojurescript or coffeescript. This feature is already implemented as a
Firefox extension (closure inspector) that reads a mapping file generated by
the google closure library.

Given the closure library can already create the mapping file between the
javascript it compiles from and its result, how hard do you think it would
be to generate the first part of the mapping: between the .cljs input file
and the javascript generated by the ClojureScript compiler ?

If you want to read more about this feature, here are some links:
