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

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.
