if bar is an integer it will be 0, if its an Integer it will be null.
The Q is do we make Integer work like the primitive, or do we make it
work like an Object.<br>

OK, this much is clear: <br>
<br>
Foo(field == null) can be true if field is null.<br>
<br>
but, what about Foo(field > 3), and field is null? should that be
false? what about Foo(field != 3) - should that be true? <br>
<br>
in SQL, null will always result in a false condition, unless you
explicitly use null.<br>
<br>
Thoughts? <br>
