With latest dmd from github, this code produces a link error:

class Node
{
    int id;

    this()
    {
    }

    this(int tok)
    {
        id = tok;
    }

    mixin template ForwardCtorNoId()
    {
        this() {} // default constructor needed for clone()

        this(int tok)
        {
            super(tok);
        }
    }
}

class Derived : Node
{
    mixin ForwardCtorNoId!();
}


void main()
{
}

This does not happen with dmd 2.060 and using bisect, it seems to be introduced
with this commit: 8bc59cfe8e6896435f20ce1e9bdcc226942f59a8 fix Issue 5893 -
Allow simple aliases for operator overloading

A work around seems to be to move the mixin declaration out of the base class
scope.
