What realistic use case do you have for caring about whether two integers of the same value are distinct objects? Modern versions of Python warn about doing unpredicatble things with `is` exactly because you are not supposed to do those things. Valid use cases for `is` at all are rare.

There might not be that many of them, depending on how you count, but they're not rare in the slightest. For example, you have to use `is` in the common case where you want the default value of a function argument to be an empty list.
