or

sub comparifier {
  no warnings 'uninitialized'; # because blessed() and reftype() can r
+eturn undef.
  blessed($_[0]).reftype($_[0]).$_[0]
  eq
  blessed($_[1]).reftype($_[1]).$_[1]
}

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]
}
