Template::TT3::Type::Undef is a specialised subclass of
Template::TT3::Type
used in conjunction with
Template::TT3::Variable::Undef
for representing the undefined value,
undef.
It inherits everything from the Template::TT3::Type base class, including methods like defined() and undefined() which can be used as virtual methods to test if a value is defined or not.
