I was talking about "definite assignment", i.e. the _lack_ of automatic initialization.

I know. How does that fit in with default construction?

They aren't called unless the user calls them.


        void Bar<T>(T value) { }
        
        void Foo<T>()
                where T : new()   // generic constraint for default constructor
        {
                T uninitialized;
                T initialized = new T();
        
                Bar(initialized);  // error
                Bar(uninitialized);  // OK
        }
        
        void Test() { Foo<int>(); Foo<Object>(); }


D could take a similar approach.
