Change that to:

    {
      return t.template get<0>();
    }

Actually, there is a get member. The problem was that the compiler 
didn't know the type of t when compiling the function (because t is a 
template dependent name), so you need to tell it that 'get' is a 
template method. Because it didn't know that, it assumed the angle 
brackets were actually 'less than' and 'greater than' symbols, leading 
to the confusing error messages.
