Our goals...
A powerful engine to invent (y)our future
Pharo is a vehicule Pharo is not at its end, just starting
Pharo is not our dream, it is what we have
But **every** single day we improve it
Enabler“One of the things that drew me to do the Delay refactoring, is simply that I could. That is, I was amazed that I could dig so deep so easily, see a path to improvement and effect change at a fundamental level. Excepting complexities with the Continuous Integration due to “changing the wheels on the car at 100km/h” (and one slip), it seems to have gone reasonably smoothly. That sense of mastery is seductive.”
Enabler: Turtles all the wayA Bryant developed Seaside in Pharo ancestor (while he knew ruby, python, scheme, C, objective-C) because he could manipulate the stack behind the back of developers. Seaside is based on stack on-demand reification.
An ecosystem where innovation/business bloom
We want that **you** can make money with Pharo. We want to be able to invent solutions to existing problems.
!
We want a powerful innovative dynamic language where we can build our future.
We are a cool community

Simplicity and elegance
Simple but complete object model
Syntax fits on a postcard!
Less is more!No constructors, no static methods, no operators
No type declaration, no primitive types,
No interfaces, no need for factory
No packages/private/protected modifiers
No parametrized types
No boxing/unboxing
Still powerful
Object model
Everything is an object instance of a class !
Single inheritance !
Public virtual methods !
Protected field
