The first few paragraphs you wrote, which I elided, are a great
explanation of why things work in ways that might be unexpected,
and by including in the descriptions other things that might be
unexpected, it helps people realize that the need to understand
what the operators really mean, when applied to classes, rather
than numbers. Of course, even floating point number operations
and integer division only approximate mathematical reality, if you
are looking for more examples.<br>
<br>
But the beginning phrase about "insanity" should probably be
elided in documentation, yet the body could very well be
appropriate for tutorial documentation, even if not reference
documentation, although I'd not object to finding it there.<br>
<br>
The last phrase, about it being a PEP 495 goal to change that,
might be true, but if it changes it, then it would be a confusing
and backward incompatible change.<br>

That's what the politicians gave us. These are datetime objects, not
mathematical numbers.<br>
