Good, I will implement this and submit a slice. Thanks.

They make sense for package environments, as one of them may include a class as it defines extension methods for it, but itâs not defining the class itself. Now #includesClass: is redefined in all environments, but #definesClass: is not redefined anywhere except for package environment. So for example ClassEnvironment says that it defines every class that itâs asked about. Should we redefine that method in each environment?

Access to Inria contribution server for pillarhub

by mikefilonov

Hello pharo-dev, Torsten suggested to create a CI job for PillarHub at https://ci.inria.fr/pharo-contribution/ to build one-click image for the project. I'll be really happy to do so. I registered at https://ci.inria.fr so I need a permision to be granted for my user in order to proceed. Is here anyone who can help me with this?

[Pharo4] Slots: Class Definition

by Marcus Denker

Now classes with special Slots are shown with a special class definition (this is just a stand-in, not finalâ¦ e.g. we need to add first class globals and think about what to do with #categoryâ¦ so we will see. For now please treat this as just a stand-in for playing with things. The idea is that we need to actually use it and then see what to change in the next iteration. And it should stay always compatible: if you do not use special slots, it is compatible, if you do, you get more power at the price of not being portable to other systems. But even in this case, the slots do give value: e.g. we will be able to add very very easily breakpoints or reflectively change behaviour for a slot (without chaining its definition). This will be very powerful. Marcus
