My personal opinion is to disagree. To me, NULL means "empty". It is not
the same as a zero length string. But empty is empty, thus NULL=NULL.
Nitpicking that NULL != NULL, is only making our life harder.
Last week, there was a similar discussion going on, on the Perl6 mailing
lists, with regards to NaN (Not A Number). Is NaN==Nan, or NaN!=NaN?
