I am really looking forward to the relationship support.
I will be trying out the download this weekend.

Now we should really work to get from the prototype to a fully robust and
tested version.

Thanks Camilo - I've tried your image with the latest CogVM for Mac and it's usable.
I understand this is work in progress, are you planning to change
Object>>instVarAt: with a new primitive? or will that be handled on the image
side?
Apart from the change in the class declaration, do you think that any of the
existing code will have to be changed?
What's the biggest advantage of having slots? (and will we also have slots for
temp vars?)
Object subclass: #Rectangle
layout: PointerLayout
slots: {
#origin => Slot.
#corner => Slot.
}
classSlots: {}
globals: ''
category: #'Graphics-Primitives'
Display boundingBox instVarAt: #origin

Hi all! I was chating with Guille, who's blaming me for make a refactor in
sunit for pharo 1.4 instead of 2.0 and told me 'pharo 2.0 probably adds class
layouts and slots'. Well, i'm with a concrete type inference project, i want to
know what is made and who is in that part of the project to annoy and bore him
with questions, 'cause probably i'll want to type the slots, but i need to
understand the metaphor of the slots implementation. I want to understand too
whats implication has the class layout over the types.
