[issue9840] Recursive Repr

[Éric Araujo]

Éric Araujo <merwok at netwok.org> added the comment:

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?)
