def group_by(iterable):
     """ Yield (key, (group))'s of like values
         from an iterator.
     """
     def group(it):
         # Yield only like values.
         k = it.peek()
         while it.peek() == k:

     itr = PeekIter(iterable)
     while itr.ok():
         yield itr.peek(), list(group(itr))
