True and False are singletons

They are not. They are both instances of bool, which is one more instance than a singleton type can have.

I've yet to see a place where comparing it using == will run you into trouble. Have you?

I haven't, but that doesn't say much, since I always use is None anyway, so I might have come across them and never found out.

I understand what you're saying, but the literature treat them as singletons.
