22111	Signal can throw ValueError in debug mode	Ilya Pirogov	nobody	"Examples:

{{{
// accepts keyword-only arguments 
@receiver(signals.post_save, sender=MyModel)
def my_handler(*, sender, instance, **kwargs):
    pass


// contains annotations
@receiver(signals.post_save, sender=MyModel)
def my_handler(sender, instance: MyModel, **kwargs):
    pass
}}}


In both cases the Signal can throw an error:
ValueError: Function has keyword-only arguments or annotations, use getfullargspec() API which can support them
