O.K., as I read it, Bob's reply works convincingly if considered rather
self-contained. And with reference to typical logging situations?
(I agree that there are varying expectations regarding a log file,
one implied by the example, viz. writing only if the file is open
and silently "ignoring" the call otherwise. But this seems a rather
far fetched setup to me. I'd expect that a log file that is not in
an open state should raise, degrees of verbosity of logging being
part of configuration. A specific exception pinpoints the error.)
