Sorry about my detour into the rejected idea of a factory function.
But how about this class-based API?
class NotGiven(Sentinel):
pass
Now I can use NotGiven as the sentinel, and its default repr is <NotGiven>.
Behind the scenes we can have a SentinelMeta metaclass with all the
magic that could be required--including the default __repr__ method.
Cheers,
Luciano
