 Defaults to C<'ref'>.
 You may also want to use L<Scalar::Util/reftype>.

 The code executed when a reference of incorrect type is encountered.
 The result of this snippet is also the result of the generated code, hence it defaults to C<'undef'>.
 It's a good place to C<croak> or C<die> too.

 Be careful that in this case C<ref> must be a fully qualified function name.
