1.1.1 CQL Comparisons with NULL

CQLv2 correctly compiles equality comparisons with NULL into the appropriate expression at runtime. In CQLv1, executing

A={null}, {[A], foo :: [a-A]}

would never succeed, regardless of the value of foo.a. This is no longer the case: If A is {null} then this will execute as SELECT .... WHERE a IS NULL and if A is not {null}, it will execute as SELECT .... WHERE a = ?

See the section Removing null comparisions for the dealing with the common requirement to ignore comparisons with null.
