I've googled and found no straightforward solution to this issue. The how can I modify my code to eliminate this error?

Your code gives me a different error (Error: PowerHeap!int is used as a type).

What if you replace the SList with a dynamic array?

Thanks for your reply.

I'm sorry that I've provided wrong code. This is the exact code:

-------------------------------------------------------------------

template PowerHeap(T) {
    import std.container : SList;

    private alias PowerForest = SList!PowerNode;

    private final class PowerNode {
        private {
            T payload_;
            uint rank_;
            PowerForest children_;
        }
    }

    final class PowerHeap {
        private {
            PowerNode top_;
            PowerForest forest_;
            uint size_;
        }
    }
}

unittest {
    PowerHeap!int h;
}
