``None``, existing :class:`.Node` or :class:`.Wikicode` objects, as well
as an iterable of these types, are supported. This is used to parse input
on-the-fly by various methods of :class:`.Wikicode` and others like
:class:`.Template`, such as :meth:`wikicode.insert() <.Wikicode.insert>`
or setting :meth:`template.name <.Template.name>`.
Additional arguments are passed directly to :meth:`.Parser.parse`.
