HPy: a better C API for Python
summary
HPy presents a C API that replaces PyObject pointers with owned handles, exposes a per-interpreter context vtable and supports two CPython backends: a thin wrapper and a slower universal mode that enables a single binary across PyPy, GraalPython and CPython. It claims near-native speed, runtime debug mode switchable at import time, experimental ports live on GitHub, project began 2019 and remains alpha with packaging for universal wheels* unresolved and broader use targeted around 2023.
