Is there a reason why you want to do it file by file, as opposed to by folder?
Would something like this work for you:

class bDirectory(Directory):
    def __init__(self):
        self.my_statics = StaticDirectory($(file system path to here}+'/static',
                           list_directory=True,
                           cache_time=${http cache time, in seconds},
                           follow_links=True)

     def get_exports(self):
         yield("static", "my_statics", None, None)

     def index[html](self):
         def render[html]():
             """
              Static file here!
             """

Note that this way you could put as many files as you want under b/static/. You
may even symbolically link to any other folder elsewhere on your file system --
this could be very useful if your static files are managed separately, e.g. a
third party javascript package.
