One man's constant is another man's variable.

Functions delay binding: data structures induce binding. Moral: Structure data late in the programming process.

If a program manipulates a large amount of data, it does so in a small number of ways.

Symmetry is a complexity reducing concept (co-routines include sub-routines); seek it everywhere.

It is easier to write an incorrect program than understand a correct one.

Not many foreigners know what “loup” means in France when it’s not the
male wolf that is being refered to. If you come to learn French in
Nice, you will know that ‘le loup (in the Mediterranean)’, or “bar”
(as it is called in the Atlantic) means “sea bass” in English,
“lubina” in Spanish,  “Wolfsbarsch” in German, “baixo do mar” in
Portuguese, “mořský okoun” in Czech, “морской окунь” in Russian,
“branzino” in Italian, “mare bas” in Romanian, … One of the best fish
in ‘western seas’. I can’t guarantee that all of the translations are
