I also really like this idea. Though I wonder if it might be a better fit for `contextlib` rather than `os`? Can see arguments both ways (and it's a minor detail, anyway).

I sometimes write Python scripts which need to work in specific
work directories.

When putting such code into functions, the outer function typically
does not expect the current work dir (CWD) to be changed, so wrap the
code which need the (possibly) modified CWD using a simply context
manager along the lines of:

class workdir:
   def __init__(self, dir):
       self.dir = dir
   def __enter__(self):
       self.curdir = os.getcwd()
   def __exit__(self, *exc):
       return False

Would there be interest in adding something like this to the os module
as os.workdir() ?

I've needed (and implemented my own version of) this often enough that
I'd be in favour of it. Of course, as you show, it's not hard to write
it yourself, so I can live with it not getting implemented, too :-)
