Data::Compare:

use Data::Compare; print "same" if Compare( $ref1, $ref2 );
But be aware that Data::Compare may not necessarily do the right thing in the rare case that you try to compare an object which overloads the stringify or numify operations.

Struct::Compare:

use Struct::Compare; print "same" if compare( $ref1, $ref2 );
CAVEAT: Struct::Compare doesn't handle blessed refs.
