e.g.

interface IContainer
{
    . . .

    Class Container
        : public IContainer
    {
        . . .
    }

    alias Container selected_type;

    // static selecting_type   hack;

}


. .  .

template BaseSelector(T)
{
//    alias   typeof(T.hack) selected_type;
 alias T.selected_type  selected_type;
}


I have to use the commented "hack" lines.

I really need a compilable example. Exactly how are you instantiating BaseSelector? The reason I always ask for complete examples is I cannot count the number of times I've mocked up an example based on the complaint's description, only to find that it works fine. There was something else causing the problem that wasn't mentioned in the description that the person assumed was irrelevant.

Sure. Let me try and come up with one.

I'm working too fast. I already submitted one of these, under the "Aliases not passed down to child classes" thread.
