I'm open to suggestion on alternatives.
The problem is that there is nothing in the range of most of the primitive types
(byte, char, int, long) that corresponds to a "null" value for an object
reference. The only thing we can do is:
* Pick one particular value to be ambiguous ("did the user
really type a zero or not?").
* Throw a conversion exception, which just throws the
same decision back up a level.
