yeah, exactly.

From a rules point of view - do we care about nulls? for numbers? I guess numbers can be special if needed - any type can be treated specially.

maybe for numbers null == 0 ?

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.

OK, this much is clear:

Foo(field == null) can be true if field is null.

but, what about Foo(field > 3), and field is null? should that be false? what about Foo(field != 3) - should that be true?

in SQL, null will always result in a false condition, unless you explicitly use null.

Thoughts?

Michael.
