I tested 4.0.4 with NULL provided via a bind variable to the WHERE clause, and
it rejects the query.

> In SQL, any comparison with NULL is NULL, which is interpreted as FALSE in a
> condition. To test for NULLness, you use IS NULL or IS NOT NULL.
> But LWT uses IF col = NULL as a NULLness test. This is likely to confuse
> people coming from SQL and hamper attempts to extend the dialect.
