PEP 749 / 3.14 regression: Method annotation incorrectly resolves to method itself when method name matches imported type #143306
Description
Bug report
Bug description:
When a method name is the same as an imported type used in its return type annotation, Python 3.14's PEP 749 annotation resolution incorrectly resolves the annotation to the method itself instead of the imported type.
This is a regression from Python 3.13 and breaks tools like Sphinx that introspect annotations.
Expected Behavior (Python 3.13)
from datetime import date
class Example:
def date(self) -> date:
return date(2025, 1, 1)
import inspect
print(inspect.signature(Example.date).return_annotation)
# <class 'datetime.date'>Actual Behavior (Python 3.14)
from datetime import date
class Example:
def date(self) -> date:
return date(2025, 1, 1)
import inspect
print(inspect.signature(Example.date).return_annotation)
# <function Example.date at 0x...>Reproducer
