Kilon, great reflection. We should have Pharo display Pharo Zen as exposed in Pharo Vision:
Pharo Zen Our values and convictions are condensed in this simple list. Easy to understand, easy to learn from, easy to change. Objects all the way down. Examples to learn from. Fully dynamic and malleable. Beauty in the code, beauty in the comments. Simplicity is the ultimate elegance. Better a set of small polymorphic classes than a large ugly one. Classes structure our vocabulary. Messages are our vocabulary. Polymorphism is our esperanto. Abstraction and composition are our friends. Tests are important but can be changed. Explicit is better than implicit. Magic only at the right place. One step at a time. There is no unimportant fix. Learning from mistakes. Perfection can kill movement. Quality is a emerging property. Simple processes to support progress. Communication is key. A system with robust abstractions that a single person can understand. :D best nacho *Lic.
