Is there such a thing as a Singleton template that actually saves
programming effort?
Is it possible to actually use a template to make an arbitrary class a
singleton without having to:
a) explicitly make the arbitrary class's constructor and destructor private
b) declare the Singleton a friend of the arbitrary class

foo() generates elements with event handlers that invoke foo function
properties.
Is this an abhorrent or misthought pattern ?
It allows just the one occurence of identifier /foo/ to be changed to
/whatever/ when need arises and everything should still work.
function foo () {
var callee = arguments.callee

Hi,
I've done some progress in writing a rather simple

I've been suggested reading "Modern C++ Design" or similar
books, but I feel there are full of clever guys here
who could help me out.

I'm writing an application that will run as a Web Service. It will
communicate with some old COM DLLs. These COM objects need to be
called on their own thread. In a regular Web Service I would create a
pool of objects that I call so I don't have to instantiate, log in,
etc, on each Web Service call.
How can I do this? Are there...

Design Pattern: The Singleton
Overview
Use the Singleton Design Pattern when you want to have only one instance of a class. This single instance must have a single global point of access. That is, regardless of where the object is hidden, everyone needs access to it.
The global point of access is the object's Instance() method.
