It also raise another question: does these primitives support mirror approach? (when it can be called with receiver as first argument?)

Another example is a logo turtle. With or without animation.

Doru I would like to see the laserGame implemented in Bloc (because it does not need widgets). and it will be a real example.

Immutability support

by Norbert Hartl

Does anyone know the state of immutability support in vm and image? The latest vm downloadable is compiled with IMMUTABILITY=1 (Esteban said that). When I open a pharo6 image with this VM and do: ASUser new setIsReadOnlyObject: true; name: 'foo' with ASUser>>#name: arg1 name := arg1 I don't get an exception. Is there something missing or am I not understanding? Norbert
