What I want to know is why you're willing to assert that absence of a clock of a particular configuration is an Exception, when that absence clearly documented to be a common case?
An error or not an error depends on how people will use the API. I usually don't like error codes -- people tend to ignore them or check lazily. If some library would do
(get_clock(THIS) or get_clock(THAT)).clock()
I want to get a clearly defined and documented clock-related error, not some vague "AttributeError: 'NoneType' object has no attribute 'clock'".
The error won't be that vague -- it will include that offending line, making the problem easy to track. ~Ethan~
