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.
