Awesome, this should be in the standard lib os module.
Does anyone know why is pushd and popd not included in the python's standard os module yet?

Thanks, nice.
what is the function
pushd
for? Doesn'twith PushdContext(PATH)
do the same? And why do you implement cwd and originaldir as class members? Doesn't that conflict when you use that class in a nested way?
