cpython/Lib/typing.py

Lines 1021 to 1030 in a1284e9

	def evaluate_forward_ref(
	forward_ref,
	*,
	owner=None,
	globals=None,
	locals=None,
	type_params=None,
	format=annotationlib.Format.VALUE,
	_recursive_guard=frozenset(),
	):

type_params here is None, not _sentinel, so the deprecation warning is never shown.
