'open' is preferred when you are opening a file, 'file' is preferred when
it is the type you want. That way you leave open the option to intercept
the 'open' action without interfering with tests against the type.
I guess in a similar way you should prefer the overridable sys.exit()
function rather than using the exception directly.
