/  A program should be light and agile,   \
| its subroutines connected like a        |
| strings of pearls. The spirit and       |
| intent of the program should be         |
| retained throughout. There should be    |
| neither too little nor too much,        |
| neither needless loops nor useless      |
| variables, neither lack of structure    |
| nor overwhelming rigidity.              |
|                                         |
| A program should follow the 'Law of     |
| Least Astonishment'. What is this law?  |
| It is simply that the program should    |
| always respond to the user in the way   |
| that astonishes him least.              |
|                                         |
| A program, no matter how complex,       |
| should act as a single unit. The        |
| program should be directed by the logic |
| within rather than by outward           |
| appearances.                            |
|                                         |
| If the program fails in these           |
| requirements, it will be in a state of  |
| disorder and confusion. The only way to |
| correct this is to rewrite the program. |
|                                         |
