Agreed. Assignment-as-expression is nicer. But I have to say I've
never really missed it in Python until this discussion started.

Question. Do you object to assignment-as-expression per se, or merely
as the default way of looking at assignment? Or to put it another way,
would something like my x := val (or maybe x <- val or something else)
be acceptable?

Paul.
