I don't recognise the term "class singleton". Can you explain please? How 
is it different from an ordinary singleton?

For the record, I ended up deciding that I didn't need any special 
objects or metaclass programming, just a factory function which returned 
a regular instance. But reading the thread has been a good education for 
me, thanks folks.
