Need Help??

in reply to How do I test the deep equality of two hash tables?

Another way to compare to arbitrarily complex data structures is to use canonical serialization. Storable is one module that provides this capability.

For example:

use Storable;

sub deeply_equal {
  my ( $a_ref, $b_ref ) = @_;
  
  local $Storable::canonical = 1;
  return Storable::freeze( $a_ref ) eq Storable::freeze( $b_ref );
}
