That is a VERY interesting pattern:


      with source.walker as walker:
            def ignore(name):
                return match_pattern(ignore_patterns, name)


            @walker.folder_visitor
            def visit_folder(folder):


Make the context be the source of the decorators, and do the iteration on
__exit__.

This could work for me, but you must admit it is very much twisting context
managers arms to the extreme.

      with self.closure() as c:
             @c
            def *_*(): match_this() match_that()

I'd like the above to be something like (warning:new keyword ahead):

      within self.closure():
match_this()
 match_that()

A clean, anonymous block.
