Now I know I can bypass this with the -d switch but I'm more interested
in fixing the problem than bypassing it.

There is a trick based on explicit alias to avoid those errors. I'd like the 
idea of using this alias to be present in that error message...

Bye,

Please do share. I thought the concept explicit alias simply requires me 
to do his:

alias ListWrapArray LWA;
mixin LWA!(Image, _images,
        _adding, _added,
        _blankListCallback!(Image), _removed,
        false, false, false);

This did not work... resulted in the same error. On closer look it seems 
the actual problem is not the template but the definition of "insert" 
therein. It is being hidden by the definition of insert in ImageCollection.

ImageCollection definition:

        void insert(int index, Image img)
        {
                if(index >= _images.length)
                {
                        add(img);
                }
                else
                {
                        assert(0, "Must add images to the end of the image 
list");
                }
        }

ListWrapArray definition:

        void insert(int index, TValue value)
        {
                _insert(index, value);
        }

In the end it turns out to be the same problem as one and two. Any 
suggestion on how to deal with these correctly? I can resolve this 
particular error by renaming the function to "Insert" in 
ImageCollection. But even though it appeases the compiler, is that the 
correct solution? Is there something else that I'm not taking into 
consideration? How do I fix the other two since there is no way to 
rename opApply and opCmp that I'm aware of?

Thanks
