I don't think it would, because it still requires that procs be grouped together in the source code, as well as funcs.  Something like

    code: (proc | func)*

would be more accurate, but then I still have my same tree problem.

Though your idea did trigger some vague notion in my brain meaties that maybe I can do a combo top-down and bottom-up visitor to bubble procs and funcs apart...  I'll have to think about this.

Other ideas?
