I have a routine from Randal Schwartz's site at: http://www.stonehenge.com/merlyn/UnixReview/col30.html called deep copy which copies the contents of a reference to stuff in a deep manner rather than just copying the pointers.
My problem is it loses the object information if it's copying objects.
Any one have any idea of how to modify the routine to handle objects?
my $arrayObjsRef = \@arrayOfObjects;
my $copy = _deep_copy( $arrayObjsRef );


sub _deep_copy
{
   my $this = shift;
 
   my $ref = ref $this;
   
   if ( not ref $this )
   {
      $this;
   }
   elsif ( ref $this eq "ARRAY" )
   {
      [ map _deep_copy( $_ ), @$this ];
   }
   else
   { 
     # this is where the objects would be copied
      +{ map { $_ => _deep_copy( $this->{$_} ) } keys %$this };
   }
}
