this code:

class T(int i)		// line 1

}

void main()
{
	T!(1) t = new T!(1);
}
^^^^^^^^
gives these errors:

(3): template instance T is not a template declaration, it is a class
(3): T!(1) is used as a type
(5): template instance T is not a template declaration, it is a class
(5): T!(1) is used as a type
(11): T!(1) is used as a type

What an I doing wrong?

Try this:

class T(int i)        // line 1
{
     T dup()
     {
         return new T();
     }
}

void main()
{
     T!(1) t = new T!(1);
}

Thanks!!

Now, how about this:


class T(int i)        // line 1
{
     T!(i+1) inc()
     {
         return new T!(i+1)();
     }
}

void main()
{
     T!(1) t = new T!(1);
	T!(2).T t2 = t.inc();
}


can you use a template inside it's self?

Try .T!(i+1)
