C API: Add PyObject_GenericHash() function · Issue #113024 · python/cpython (original) (raw)
Feature or enhancement
Just added Py_HashPointer() function can be used to implement the default Python object hashing function (object.__hash__()), but only in CPython. In other Python implementations the default object hash can depend not on the object address, but on its identity.
I think that we need a new function, PyObject_GenericHash() (similar to PyObject_GenericGetAttr() etc), that does not depend on CPython implementation details.
