or if you did

  $b = $a;
  $b->equals($a);

bcm@void:~ > perl -e '$a = {}; $b = $a; print "a: $a\nb: $b\n"'
a: HASH(0x814374c)
b: HASH(0x814374c)

i guess it depends on your definition of object identity:

1) are two data structures with equivalent values defined as
equal?

  $a = {foo => 1};
  $b = {foo => 1};

2) (i don't know if i'm using the correct vocabulary) are
two variables referring to the same reference defined as
equal?

  $a = {};
  $b = $a;
