You had said "that’s easier to implement than not having them" which is what's being objected to there as being plainly incorrect. To your infix comment, for example a strict left to right scan works just fine and is trivial to implement. In that example I guess you'd still strongly prefer to retain precedence for the assignment operator in order to avoid an extra set of parentheses around every expression but that has no effect on the ease of implementing the language itself.
