for example although XML::Twig inherits from XML::Parser it explicitly instantiates a Parser object inside its constructor, but it looks in Perl that is explicit and optional. I m confused about if I can use a base class instance in place of a derived instance polymorphic wise? Are base and child classes connected polymorphicaly?
