Re: Date.prototype.toISOString and Invalid Date

NaN is already part of the ECMAScript language. There is an underlying Number representation of Date, but I'll grant you it's not a perfect fit as there are no Date literals. Returning null is another option, I suppose, but one that's likely to create even more problems.

In fact, "NaN" is an abbreviation of an English phrase, namely "not
a number".  But neither dates nor date strings are numbers.  What say
you to "NaD"?
