:c:func:`!_PyObject_CallMethodId`, :c:func:`!_PyObject_GetAttrId` and
:c:func:`!_PyUnicode_FromId` are deprecated since 3.15 and will be removed in
3.20. Instead, use :c:func:`PyUnicode_FromString()` and cache the result in
the module state, then call :c:func:`PyObject_CallMethod` or
:c:func:`PyObject_GetAttr`. Patch by Victor Stinner.
