But why change anything? In my opinion there seems a certain symmetry
which is obvious to anyone reading the code. Just because a call
to Z() is repeated is not a problem because it is only called once,
either way.
Clarity is better than obscurity, especially when it is clarity in
code whereas obscurity in code just to avoid repeating something
is pointless. (I better clarify that... using loops and so on is
not what I am talking about).
