AFAIK, if T==int, then std.conv.to should simply alias itself 
away. And
it *should* be able to handle ctors that take the requisite 
type, I
think.

I use:

        foreach (T; IntegralTypeList)
        {
                assert(factorial(cast(T)3) == 6));
        }

I works, but looks a little strange.
I belive that compiler should optimise this (do nothing), but I 
am not sure.
