compiler complains:
testclass.d(21): mixin dup isn't a template

This illustrate the bug a little more clearly, and also fix some issues of the
original code.
import std.stdio;
template dup(T){
    T dup(){
    auto c=new T;
    foreach(i,x;this.tupleof)
    {
        c.tupleof[i]=x;
        writefln(`tupleof `,x);
    }
    return c;

    }
}
class baseclass
{
//    mixin dup!(baseclass);           // comment this , the dup won't be
hidden anymore in the derive class
    void method(){printf("a.method\n");}
}
class deriveclass:baseclass
{
    mixin dup!(deriveclass);
    int j;
        float i;
    void method(){printf("b.method\n");}
        this()
        {
                i=34;
                j=10;
        }
}
void main()
{
    deriveclass mybinstance = new deriveclass;
    mybinstance.dup();
}
