This is (if we are positive) an internal implementation detail and (if we are negative) a bug in CPython. There is no way to define in pure Python a list-like type that would have the exact same behavior. We already have one such special case for __add__/__radd__ on subclasses of strings and unicodes, which appears to be the use case that people rely on most often, but I don't see the point in duplicating this strange behavior for lists, tuples, and so on, unless there are really several programs out there that rely on it.
