Hi Stefan, I'm interested in experimenting with a moving GC in CPython, but also by modifying the C API to make sure that it is efficient on PyPy or another Python implementation which uses a moving GC.
As Carl in the other thread, currently, other Python implementations have to emulate PyObject** which is inefficient. Right now, the C API is an exact mapping of CPython internals which prevents us to enhance or optimize CPython, but also makes other Python implementations inefficient when running C extensions.
