[New-bugs-announce] [issue32464] raise NotImplemented vs return NotImplemented

[Srinivas Reddy T]

New submission from Srinivas  Reddy T <thatiparthysreenivas at gmail.com>:

I ran these queries on cpython repo.

➜  cpython git:(master) ✗ grep -r . -e return  --include=\*.py  | grep NotImplemented | wc -l
196

➜  cpython git:(master) ✗ grep -r . -e raise   --include=\*.py  | grep NotImplemented | wc -l
295

I have always used raise NotImplemented or raise NotImplementedError. But when does it make sense to return NotImplemented?
