Sorry, I was away last week, but that's exactly it.
Making it 'virtual' means the computer needs to store extra information in the class, since it doesn't know what functions to call it it from the type it's supposed to be alone.

Hi,
I believe the next code is wrong:
class Egg {
Egg e;
int i;
Egg(int ii=0) : i(ii) {}
};
because you would end up with an endless definition (memory allocation) of Egg objects, thus int i.
Ok, so God Eckel proposes for a singleton:
class Egg {
static Egg e;

extutils::xspp::node::method
ExtUtils::XSpp::Node::Method(3pm) User Contributed Perl Documentation ExtUtils::XSpp::Node::Method(3pm)
NAME
ExtUtils::XSpp::Node::Method - Node representing a method
DESCRIPTION
An ExtUtils::XSpp::Node::Function sub-class representing a single method declaration in a class such as
class FooBar {
int foo(double someArgument); // <-- this one
}
METHODS
new
Creates a new "ExtUtils::XSpp::Node::Method".
Most of the functionality of this class is inherited. This means that all named parameters of ExtUtils::XSpp::Node::Function are also valid
for this class.
Additional named parameters accepted by the constructor: "class", which can be an ExtUtils::XSpp::Node::Class object, "const" and "virtual"
that are true if the method has been declared "const" or "virtual".
perl_function_name
Returns the name of the Perl function (method) that this method represents. It is constructed from the method's class's name and the
"perl_name" attribute.
is_method
Returns true, since all objects of this class are methods.
ACCESSORS
class
Returns the class (ExtUtils::XSpp::Node::Class) that the method belongs to.
virtual
Returns whether the method was declared virtual.
set_virtual
Set whether the method is to be considered virtual.
const
Returns whether the method was declared const.
access
Returns 'public', 'protected' or 'private' depending on method access declaration. By default, only public methods are generated.
