And we return to where we started. Although I personally prefer 
Py_REPLACE/Py_XREPLACE, I'm afraid that using them would look like I 
just ignore the results of the poll. Because Py_SETREF looks good for 
most developers at first glance, I hope this will not lead to confusion 
in the future. If there are no new objections, I will commit the trivial 
auto-generated patch today and will provide a patch that covers more 
non-trivial cases. Now is better than never, and we have been 
bikeshedding this too long for "right now".
