Sorry, years of python programming have made me shy of

That is error-prone!
In Python you are supposed to use the with-statement to get RAII
like behaviour. So you use __enter__ and __exit__ methods on the
context-manager. From the Python docs:
«The context manager’s __exit__() method is invoked. If an
exception caused the suite to be exited, its type, value, and
traceback are passed as arguments to __exit__(). Otherwise, three
None arguments are supplied.»
See, even Python supports this. :-)
