For those semantics, I think one of the following would be better:

    with local(obj):

    with scoped(obj):

but those semantics apply better to __enter__ and __exit__ anyway.

I think a "closing adaptor" should only work with objects that have a
close() method.

Perhaps:

    with scoped_closable(obj):
