That can result in false positives.

my $r = \@a; print comparifier($r, "ARRAY$r") ?1:0,"\n"; # 1

    True enough.

    sub comparifier { no warnings 'uninitialized'; # because blessed() and reftype() can + return undef. my $sep = pack 'N', rand 2**15; blessed($_[0]) . $sep . reftype($_[0]) . $sep . $_[0] eq blessed($_[1]) . $sep . reftype($_[1]) . $sep . $_[1] }
    Between the mind which plans and the hands which build, there must be a mediator... and this mediator must be the heart.
