Comment (by rws):
Replying to [comment:30 vdelecroix]:
> What I need is a method that either returns a reliable answer `True` or
`False` or raise an error which can either be `This comparison is
meaningless` or `I don't know how to compare this`.
Then `bool( == )` is right for the moment and may be replaced with #19040.
As said don't be surprised if it takes a long time.
