Hmm, it seems like I must write my own Master Foo koan (this is a first
draft only, improvements welcome):

After Master Foo completed his discourse on the Unix nature <
http://www.catb.org/~esr/writings/unix-koans/unix-nature.html>, a tall,
thin, gray-haired, balding, bespectacled man entered the room.

Master Foo looked up from his lectern.

"Greetings," said Master Foo.  "Who are you?"

"I am the Master Planner," said the Master Planner.  "Ninth of my dharma
line," he added modestly.

"I am Master Foo," said Master Foo.  "What do you plan for?"

"To reach enlightenment by concentration on a single focus," said the
Master Planner.  "Therefore I remove all that is unnecessary from my life."

Master Foo said nothing, but began to type fiercely.  Those students who
could see what he was doing were astonished that he appeared to be typing
complete gibberish.

When he stopped typing, Master Foo pushed the device to the Master
Planner.  "Read me, if you would, the last maxim of the Zen of Python."

The Master Planner appeared as astonished as the students.  "But all men
know that the twenty-one maxims of the Zen of Python have been unchanged
since the Master Sorter wrote them down long ago!" he protested.

"Nevertheless," said Master Foo softly.

The Master Planner gave the words of command and then spoke very softly.
"It says -- it says, 'Inclusion is better than exclusion.'"

On hearing these words, all present were enlightened.
