Also, I think there no need in NEWS entry. But if someone want it - I'll add it.

I do not think that silencing TypeError for any operation is right. It can silence some unexpected errors, it is also not very efficient. It would be better to just not try to perform unsupported operation. I suggest to add an optional parameter in _operator_fallbacks() to specify whether try to handle complex numbers or not. We know which operations are not supported by complex.

+1. This sounds like the right approach to me.

Do we need NEWS entry here? It's improves the user experience, so in my opinion - yes.

[serhiy-storchaka]

This is a user visible change, so a NEWS entry will not make bad.

It will help if users wonder about confusing error messages in older Python.

LGTM, modulo minor nitpick about default value.
