What is it you want to do?  We recently added support for comparing with
"null".  That will match all the null_* values.  Thus allo of these are
true:
        null == null_string
        null == null_blob
        null == null_list
        null == null_function
        null == null_job

Still need to add some more tests.  It worked with the functions before,
so it should work with the value as well.
