Purpose of empty Class
class A
{};
int main()
{
A a;
}
What is the purpose of such empty classes in C++?Why is it allowed in the language specification?

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;

__________________________________________________________________________________________________________________________________________________
NAME
xowish - Graphical shell containing object-oriented scripting language XOTcl
SYNOPSIS
xowish ?fileName arg arg ...?
_________________________________________________________________
DESCRIPTION
xowish is a shell-like application that reads XOTcl commands from its standard input or from a file and evaluates them. In addition to xot-
clsh it provides graphical user interface support for TK widgets.
XOTcl (XOTcl, pronounced exotickle) is an object-oriented scripting language based on MIT's OTcl. It is intended as a value added replace-
ment for OTcl.
Scripting languages, like Tcl, are designed for glueing components together, provide features like dynamic extensibility and dynamic typing
with automatic conversion, that make them well suited for rapid application development.
The basic object system of XOTcl is adopted from OTcl. The object system enables us to define objects, classes, and meta-classes. Classes
are special objects with the purpose of managing other objects. ``Managing'' means that a class controls the creation and destruction of
its instances and that it contains a repository of methods accessible for the instances. Every object may be enhanced with object-specific
methods. XOTcl supports single and multiple inheritance. All relationships in XOTcl, including class and superclass relationships, are com-
pletely dynamic and can be introspected. Through method chaining without explicit naming of the intended method, ambiguities in name reso-
lution of methods are avoided. This way a shadowed method can be ``mixed into'' the execution of the current method.
XOTcl combines the ideas of scripting and object-orientation in a way that preserves the benefits of both of them. It is equipped with sev-
eral new language functionalities that help building and managing complex systems. We added the following support:
Dynamic Object Aggregations, to provide dynamic aggregations through nested namespaces (objects).
Nested Classes, to reduce the interference of independently developed program structures.
Assertions, to reduce the interface and the reliability problems caused by dynamic typing and, therefore, to ease the combination of many
components.
Meta-data, to enhance self-documentation of objects and classes.
Per-object mixins, as a means to improve flexibility of mixin methods by giving an object access to several different supplemental classes,
which may be changed dynamically.
Per-class mixins, as a means to improve flexibility of mixin methods to a class, all instances of the class have access to the mixed in
methods like for multiple inheritance, but without the need of intersection classes.
Filters as a means of abstractions over method invocations to implement large program structures, like design patterns.
Dynamic Component Loading XOTcl integrates the Tcl package loading with architectrual support for integration with object-oriented con-
structs. Moreover, it provides tracking/tracing of component loading.
