Or a web page converts some value to a string using `"" + someValue`, in 
which case adding a toString() legacy mode is not sufficient, because 
valueOf() is actually invoked (well, except for Date.prototype because 
of its @@toPrimitive override). Does that mean valueOf() also needs to 
have a legacy mode to special case the prototype object?
