The experience in this thread of most supporters failing to get the semantics right shows that this isn't an extra day to learn. It's something that experienced programmers would continue to get won't in edge cases after years of use. The proposed operators don't match how most experienced developers think about code. Being glaringly ugly as written, and using an unintuitive or counterintuitive symbol alternates that, of course. I can hardly imagine a stronger bug magnet than PEP 505.
