    Description

      Using `pyside6-metaobjectdump` on this MWE will fail

      AttributeError: 'Call' object has no attribute 'id'
      
      from abc import ABC, abstractmethod
      from PySide6.QtCore import QObject
      
      class Dialog(ABC):
      
          @abstractmethod
          def execute(self) -> bool:
              raise NotImplementedError("User must define 'execute' to use this interface")
      
      class MyMetaQMLClass(type(QObject), type(Dialog)):
          pass
      
      class MyQMLObject(Dialog, QObject, metaclass=MyMetaQMLClass):
          pass
      

      Looking at the source in metaobjectdump,

      def _name(node: Union[ast.Name, ast.Attribute]) -> str:
          """Return the name of something that is either an attribute or a name,
             such as base classes or call.func"""
          if isinstance(node, ast.Attribute):
              qualifier, name = _attribute(node)
              return f"{qualifier}.{node.attr}"
          return node.id
      

      I don't know why the node doesn't have an id, but maybe the way we create our metaclass is wrong? It fails on the `(` in class MyMetaQMLClass*(*
