PEP 572: Python assignment expressions has been accepted

It feels like we are repeating a mistake the PHP community made years ago. PHP supports assignment in expressions, and the community seems to avoid its use. There are plenty of examples of stackoverflow questions and answers where the problem is caused by coders overlooking an assignment in an expression. You just don't expect assignment to occur in an expression, and its visually similar enough to gloss over it.

On the other hand you can assign within expressions in Rust, and it's generally not been an issue that I've seen anyone complain about. However, that might be because the type checker usually catches you if you're making a mistake; assignment/variable binding return the type `()`, which doesn't work inside ifs or whiles
