How do you prevent people from instantiating Object (in your example)?

Also, I was more or less looking for a member-specific way of doing the singleton access. For example:

Object::instance()

Hi,

At the bottom of

http://uint32t.blogspot.com/2007/12/you-lazy-bastard-part-1.html

there is a simple class that I've used. The usage would look something
like:

struct Object {...};

// returns Object &, lazily-initialized and threadsafe
singleton<Object>::instance();

It requires Boost Threads to be threadsafe. I apologize in advance for
the language, but didn't think it could possibly be useful :-)

I also recently came to know that there is something in the Boost Vault
under the X-files folder.

Let me know if you have any questions.
