I have a class which implements a context manager, its __init__

Along with several methods which implement functionality on

does not return an instance of itself, it merely opens a context.
I am not thrilled about is the implementation I have used and I
am wondering if there is a better way. It's been a long time since
I have worked in Python and I am probably overlooking something
obvious. Syntactically I achieve what I want in use, but it looks awkward
in its implementation. How can I clean up the first class and decorator
to implement the functionality on a method in the Foo class?

Then you just use the @contextmanager decorator on a function, have it
set up, yield the context you want, and clean up after.
