It's ridiculous because you declared an IntEnum and then started using
non-integer values that boolify to the same value (and don't intify).
If that even works, it's a total hack, and it might stop working in a
future version... for example, it doesn't seem to work on my Python
3.5:
>>> class B4(IntEnum):
... F1=0
... F2=""
... F3=None
... T=1
...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.5/enum.py", line 152, in __new__
enum_member = __new__(enum_class, *args)
ValueError: invalid literal for int() with base 10: ''
Using Enum instead of IntEnum does work, but it's still hardly a
normal use of an enumeration.
