Because you don't have to create the context manager directly in the with statement
...what? that's *my* argument. that's *precisely* why I consider open to be 'misbehaving'. Because you *should* be able to create a context manager outside the with statement without causing these problems. Because calling open outside the with statement [absent other arrangements like an explicit try/finally] causes problems that wouldn't be there for a proper context manager that has __exit__ as the inverse of __enter__ rather than as the inverse of some other operation that happens before __enter__.
