Oh, and same goes for Equals and NotEquals -predicates.

As I'm continuing writing this SQL indexing thing, I came to wonder,
is there any specific reason why both IsNull and IsNotNull predicates
exist for property and association? Because how I see it, IsNull is
just negated IsNotNull and vice versa. Would it be simpler to have
just XXXIsNull and Negation types, instead of Negation, IsNull and
IsNotNull? That could simplify some things at least in query parsing -
there would be only one way to express certain query, and not many, as
it is now.
