Then they should be fixed.  That doesn't do anything useful right now.

Show me one real example of where this would help.  I have never even 
remotely considered such a thing in my DBI programming; I have some 
convenience modules that translate undef to IS NULL when constructing 
queries, and DBI handily turns NULLs into undefs in results for me.  If 
this is not about DBMS interfacing but you want Perl to implement SQL 
expression semantics, why?  What possible benefit is there?
