Put Tuple in templates in a class fails

[Xan]

Hi,

I have this code: https://gist.github.com/2653620

and I want to change
public class Algorisme(U,V) {

to
public class Algorisme(V,U...) {

but when I do: https://gist.github.com/2653643

I get error:
prova_amb_tuples_a_Algorisme.d:84: Error: 'alg' is not of 
arithmetic type, it is a 
prova_amb_tuples_a_Algorisme.Algorisme!(int,int).Algorisme
prova_amb_tuples_a_Algorisme.d:84: Error: 'alg2' is not of 
arithmetic type, it is a 
prova_amb_tuples_a_Algorisme.Algorisme!(int,int).Algorisme



What fails?

Thanks in advance,
Xan.
