Subject: [ruby-talk:20790] singleton help

I need some help with a singleton class.

1.  With 'new' made private and replaced with 'instance',  how do I properly 
pass in the arguments that would normally go to the 'initialize(...)' method 
via 'new'?  Just use setter methods?

2.  If I subclass a singleton class, then create an instance of that 
subclass, do I get the same instance with the additional behaviour of the 
subclass?

These questions probably reveal my ignorance about singletons.  Perhaps, a 
singleton is inappropriate for what I am trying to do.  I need a single 
instance of a class that has the common and different behaviour associated 
with subclasses.  I would greatly appreciate any help or advice and possibly 
URLs to additional info on singletons.  

Thanks ahead,

Albert
