Declare as:

     void opDispatch(string name, T...)(T values...)
                                                ^^^

What? I am using code like Álvaro posted all the time, whereas your syntax  
doesn't even work (according to my test):

void foo(T...)(T values)
{
}

foo(42);

Error: template test.foo(T...) does not match any function template  
declaration
Error: template test.foo(T...) cannot deduce template function from  
argument types !()(int)

I wonder why it works for opDispatch (if it does, as you say).
