While we can do `A == B`, or `B == C` or `B == B`, I would expect to be able to compare like this as well: `A >= B (if B is subclass or itself of A)`, or `B <= C (if B is a subclass or itself of C)`
I think this a bad idea. It's all down to statistics: - how many times will this feature hide an error (you had classes but wanted instances) - how often do you do this type of check Anecdotally I pretty much never use issubclass. But I do sometimes miss parents so I get a class when I wanted an instance. / Anders (replying to the wrong mail because my mail client doesn't permit me to reply all to the correct one for some reason)
