Stefan Behnel <stefan_ml at behnel.de> added the comment:

I would prefer changing the builtin types instead of the macro. Especially since
changing the immutable types has the side effect of making access to their size
fast for C code.

Remember that a lot of CPython C-API code will never work unchanged in PyPy -
switching from Py_SIZE() to PyList_GET_SIZE() is really no big deal compared to
e.g. fixing up the usage of borrowed references.
