Any and all operators are bug-prone if you don't understand or remember their
precedence rules. If you want the extra protection against precedence
screw-ups, then use parens. But I don't see any reason to _require_ them. And
honestly, I would be ticked if code like

auto x4 = x0 + y1 ? z1 : w1;

became illegal. I would never use parens here, because I find the precedence
rules in this case to be very clear. This enhancement request is trying to
enforce a particular coding/formatting style, and I'm very much opposed to
that. The compiler shouldn't care how I format my code.

Feel free to use parens to guarantee the correct order of operations if you
don't feel confortable with the precedence rules in a particular expression,
but I don't want that forced on everyone.
