So, so far, two 3rd party implementations who don’t want to see _their_ code go into the stdlib, but who are in favour of someone else writing a stdlib implementation\[1\]? That’s perfectly fair, but still leaves us with the question of who would write (and maintain) the stdlib implementation. This feels to me like a borderline case at the moment. No-one is particularly _against_ the idea, but no-one is offering to do the work. I suspect that this will go nowhere unless/until someone writes an implementation. Maybe at this point the next step should be to create a PR adding `OrderedSet` to `collections`. That might get some core dev attention and maybe a sponsor for a PEP. * * * 1. Which presumably would mean they could recommend people use the stdlib version rather than theirs in future… --- _[View the full topic](https://discuss.python.org/t/add-orderedset-to-stdlib/12730)._
