           Summary: With DList of pointers, insertBack matches multiple
                    templates.
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: nobody@puremagic.com
        ReportedBy: entheh@cantab.net

For example:

struct STRUCT {
   int field;
}

DList!(STRUCT*) list;

STRUCT struct;

//This works:
list.insertBack(null);
list.back=struct;

//This doesn't:
list.insertBack(&struct);

The error is along the lines of:

Error: template std.container.DList!(STRUCT*).DList.insertBeforeNode matches
more than one template declaration,
C:\D\dmd2\windows\bin\..\..\src\phobos\std\container.d(2054):insertBeforeNode(Stuff)(Node*
n, Stuff stuff) if (isInputRange!(Stuff) &&
isImplicitlyConvertible!(ElementType!(Stuff), T)) and
C:\D\dmd2\windows\bin\..\..\src\phobos\std\container.d(2113):insertBeforeNode(Stuff)(Node*
n, Stuff stuff) if (isImplicitlyConvertible!(Stuff, T))

Looks as if it accidentally matches the range-adding insertBack function as well as the single-entry-adding function.

(I haven't directly tested this example - I just encountered it in a bigger project. Apologies if I've got something wrong in the example.)

I don't know enough about the stuff involved to fix this. Hopefully someone who knows D better can figure out a good fix, either in the compiler or in Phobos. :)

I meant of course:

list.back = &struct;
