"Attributes from the metaclass have always been excluded from the dir() of a class."
Be that as it may, I think it is wrong. I can understand excluding methods of the metaclass, but __qualname__ (and friends) are only defined in the metaclass because they are properties and not __dict__ members, but they are regular attributes of the class, not of the metaclass.
E.g. why is __module__ in there and not __qualname__? Both are determined dynamically at class creation time.
The answer is that it's an implementation detail: there is no tp_module (or ht_module) member in the PyHeapTypeObject struct to store it, so it's stored in __dict__, while __qualname__ is stored in a struct member. |
