Add a recursive_repr() decorator to provide a solution to the problem of creating a container __repr__ method that doesn't fail for recursive calls. |

Good idea. I wonder if the genericity (being able to specify the placeholder) is needed; the ellipsis is used by built-in containers (not documented AFAICT, see #9842) and seems a good choice for most (all?) of the cases. What bothers me is that this simple, common case can’t just use @recursive_repr (without parens) which seems to me more natural. One markup glitch: :meth:`repr__` lacks two underscores. (Unimportant side question: Since collections defines __all__, why are imported names renamed with a trailing underscore?) |

FTR, the answer to my interrogation in my previous message is contained in Raymond’s PyCon talk about API design: http://pycon.blip.tv/file/4883290/ :) |
