in thread How do I test for a NULL string?

..is to explain undef and how you test for it.

Problem being 

my ($x,$y);
print "Same!" if $x==$y;
__END__
Same!

Since it doesnt follow the properties of the SQL null i'm not real sure why explaining undef will help any more than explaining an empty string.
