RE: [sv-bc] Built-in types are not packed arrays

I see your point, but section 4.2 is clearly distinguishing packed arrays
and built-in types. For example, you can't declare a packed array of bytes.

    byte legal [15:0];
    byte [15:0] illegal;

Or maybe the apparent need for $left(integer) is an argument for
disallowing bit selects of integers. But that's no longer possible,
of course, because of backward compatibility.
