the next question will likely be "so why does = exist at all?" And if we decide to make ':=' the official assigment operator and deprectate '=', the next question will be "Why do we have '==' instead of '='?" Some languages use '=' for assignment, others for equality, but do you know of a language that uses ':=' for equality' or '==' for assignment?
If Python saw '=' it could ask "Do you mean assignment ':=' or equality '=='?".
