Yes, in fact it is. However the point is more to try and get as little redundancy 
as possible. An ideal solution would never have the same expression more 
than one if the second copy is in fact the exact same. I'm sort of taking 
to an extreme the reason that it's in a template in the first place (I don't 
want to wright n almost identical function).
