While poking about the cpython source tree with reference to PEP 479,
I came across this:
https://docs.python.org/3.5/library/marshal.html
singletons None, Ellipsis and StopIteration can also be marshalled
and unmarshalled.
StopIteration is a type. I suppose it's still kinda true that there's
is it a singleton itself: StopIteration (the class) is an instance of
type, and there are *many* instances of type:
py all(isinstance(T, type) for T in [int, float, str, bool,
... Exception, StopIteration, dict, type])
True
I cannot imagine what they mean by calling StopIteration a singleton.
Why

Clearly so. Also, the special case is for StopIteration, not for its
type (just as there is for None, and not NoneType).
Nor is it a singleton itself: StopIteration (the class) is an instance of
type, and there are *many* instances of type:
