    Description

      The following code worked fine up until v6.6.2. (I tested as far back as 6.4 and up to 6.6.1 and they all worked)

      from PySide6.QtCore import QObject, Signal
      
      class Emitter(QObject):
          sig = Signal(int)
      
      class CallableObject(QObject):
          def __call__(self, x: int):
              print("emitting", locals())
      
      emitter = Emitter()
      obj = CallableObject()
      
      emitter.sig.connect(obj)
      emitter.sig.emit(1)
      

      as of v6.6.2 you now get an error on connection:

      Traceback (most recent call last):
        File "/Users/talley/dev/self/superqt/x.py", line 16, in <module>
