I don't think there's any way for you to avoid using a class 
constructor.

Thanks for the explanation. I now tried to use a class and use a 
static opIndex. But it seems from a static method you also cannot 
access the attributes of a outer class :)

class TCustomGrid: TCustomPresentedScrollBox
{       
        class ColumnsArray
        {
                static TColumn opIndex(int index)
                {
                        // Reference is defined in TCustomGrid via inheritene
			int r = getIntegerIndexedPropertyReference(reference, 
"Columns", index);
                        return new TColumn(r);
                }
        }
        
        alias Columns = ColumnsArray;
...
}

This seems like an unnecessary limitation...

Kind regards
