How to specify a QList<int> type as signal/slot argument type with pyside/pyqt

Question

My question is for pyside6, but since it may be relevant for other, I ask also for pyqt...

With pyside, you declare a slot like this :

@Slot(argtypes...)
def slot_name(self, args:type...):
  ...

With simple types, it's straightforward... But how to specify an arguent type QList<int> (or list[int]) ? (spoiler alert : pyside does not know about python type hinting system...).
