use of overload method

[hvds]

A cpangrep shows that Datify appears to have the same issue with using the coderef returned by overload::Method that I found in Test::More.

To correctly invoke XS methods I think you will need something like:

# in is_numeric
         if ( my $method = $self->overloaded($_) ) {
-            $_ = $_->$method();
+            $_ = $_->$method(undef, undef);
         }
# in objectify
     } elsif ( my $method = $self->overloaded($object) ) {
-        $data = $self->scalarify( $object->$method() );
+        $data = $self->scalarify( $object->$method(undef, undef) );
     } elsif ( my $attrkeyvals = $object->can('_attrkeyvals') ) {

(I didn't check to see if you were calling overloaded() from other modules.)

See also Perl/perl5#19388 for the proposed doc patch.
