(Off topic note)
For readability, I prefer this style:
PyDictKeyEntry *entries = DK_ENTRIES(mp->ma_keys);
while (i < n && entries[i].me_value == NULL)
i++;
But because sizeof(PyDictKeyEntry) is not 2^n, entries[i].me_value, i++
may be slower than entry_ptr->me_value, i++, entry_ptr++.
So we should prefer i++, entry_ptr++ style in case of iterating dict entries.
