It's not declared as a valid base type in CPython (subclassing would
break the invariant that there are exactly two bool values, True and
False, aka Py_True and Py_False in the C API).

	>>> class Foo(bool):
	...     pass
	Traceback (most recent call last):
	  File "<stdin>", line 1, in ?
	  TypeError: Error when calling the metaclass bases
	      type 'bool' is not an acceptable base type
