I think this doesn't work as should. This code:

struct foo {
    void opDispatch( string name, T... )( T values... ) { 
        pragma(msg,values);       // ...shows "tuple()" 
        writeln(values);                  // ...shows nothing at runtime
        foreach(v;values) {            // ...idem
            writeln(v);
        }   
    } 
}
                                                                                                           
void main( ) { 
    foo f;
    f.bar( 3.14, 6.28 );
}
