[issue22031] Hexadecimal id in reprs

That's why the change was only done in Python 3.5. To port your application to Python 3.5, you can modify you doctests to use "..." (ellipsis option of doctests).

It's better to have consistent representation of objects. Low-level debuggers like gdb uses hexadecimal, not decimal. I'm regulary using gdb, and having the memory address in hexadecimal helps.

By the way, you should never rely on the (exact) representation in your unit tests :-)
