Hello, Tim Peters. I wonder why we need to add size_t here:
assert((size_t)Py_SIZE(a) + (size_t)Py_SIZE(b) <= (size_t)PY_SSIZE_T_MAX);
AFAIK, PY_SSIZE_T_MAX = ((Py_ssize_t)(((size_t)-1)>>1)) which is signed, either
Py_SIZE(a) or Py_SIZE(b) is a positive number. Why we need to concast them to
size_t, Thank you?
