To make chdir() return a context manager *and* keep it working without calling `__enter__`, it would have to call `getcwd()`, which I've heard is expensive. So I don't think that would work, alas. On Wed, Sep 15, 2021 at 11:55 AM Eric V. Smith <eric@trueblade.com> wrote:

And I'm not crazy about the name "workdir". To me, it sounds like it returns something, not sets and resets something. But I don't have a particularly great alternative in mind: in my own code I've used "change_dir", which isn't awesome either.
Our version is named "pushdir", modeled after shell's pushd (even though pushdir is a context manager and does auto-pop). Everyone figures out what it does at a glance.
That's a great name!
Although I think having os.chdir() return a context manager is a better design (assuming it can work, but at first blush it would seem so).
