Wow -- you'd rather write nine lines of code instead of three?
clock = get_clock(THIS) or get_clock(THAT) if clock is None: raise ValueError('Cannot get clock, tried THIS and THAT')
Yes - to force people to write the last two lines. Without forcing most programmers will skip them.
Forced? I do not use Python to be forced to use one style of programming over another. And it's not like returning None will allow some clock calls to work but not others -- as soon as they try to use it, it will raise an exception. ~Ethan~
