Most of the bug tracking thread was just about whether `somedictsubclass() | somedictsubclass()` should be `dict()` or `somedictsubclass()` The latter (returns `somedictsubclass`) would cause the `|` operator to rely on the `copy()` method from `dict` which would be the only case where an operator relies on a non-double-underscores method. Based on that, two core devs were against it. The core devs prevailed, and the behaviour will be the former (returns `dict`).
