In combination with a generator, you can do many funny things.


For example, you can build up a string:

def mkstring(f):
     """Turns a string generator into a string,
     joining with ", ".
     """
     return ", ".join(f())

def create_answer():
     @mkstring
     def people():
         yield "Anna"
         yield "John"
         yield "Theo"

     return "The following people were here: " + people


Many other things are thinkable...
