#12251 added additional types it will allow, but why does it typecheck at all? For example, I wanted to pass it a ValuesList, which had come from queryset.values_list('id', flat=True), but I don't just want another type added to the assert. Can the assert be removed entirely? it should work with any iterable I pass it.
