Have you implemented the Singleton Pattern in your framework?

Yeah, MarauderIIC and I use singletons for almost every system in the engine.

I use singletons in the framework for my perl scripts.

Peter, you also use singletons in lua.

Bad practise?

I've heard a lot of people say that singletons aren't necessary, and the use of a singleton could be replaced, but I don't really know why someone would want to do so with no benefit to performance, clarity, or development time.

You can pass stuff around like a hot potato but it gets really complicated. Did you perhaps hear what to replace it with? I'm interested in any programming theory around. =)

Effectively just a sugar-coated version of slinging a pointer around.
The article and sub-article I read detailed everything that made singleton an "anti-pattern", but didn't suggest a better solution for that situation.
By the way, what do you use to implement singletons? I use a static instance that's initialized lazily. I'm going to thread my engine soon, and I don't think this is an *ideal* solution.
(PS. I tried to find the site that detailed everything wrong with the pattern, but I can't find it. If it's important, I could spend a little while retracing my steps.)
