In any case, I believe you're probably right that @@create + constructor invocation is sufficient for most use cases. The crucial step is that if the constructor returns an object, this is the object returned by |new C(...args)|. This way, the constructor can always return a cached object and ignore whatever dummy object was created by @@create. Correct? Cheers, Tom
