Yup, that would make a lot more sense.
But right now, the sizeof() obviously silently works.
As do a number of other fairly nonsensical things, like assigning a struct etc.
And yes, I realize we may well do that too. But I think that's a
dangerous pattern too, ie doing
*a = *b;
silently works, and copies everything but the final array.
And yes - none of this is _worse_ than using zero-sized arrays, but
the point is that it isn't better either.
