Re: String Reverse

  The statement

java.lang.System.out.println( "Hello!" );

  The model (?"Hello!?) is the internal storage of the code
  points H-e-l-l-o-!, the View (?println?) displays this as

Hello!

  One can as well adopt the point of view that for the string
  model it makes no sense to ?reverse? anything, because the
  same model can also be viewed as a storage of the reversed
  string, because whether to display the stored code points
  H-e-l-l-o-! as

Hello!

  or as

!olleH

  is solely a question of the View, just as the color of the
  characters used to display it or the size of the font.

  From such a point of view, every string model already /is/
  also a model of the reversed string, without the need for
  an explicit computation to ?determine? the reverse string.

  (Admittedly, this point of view is not helpful in some cases.)
