I imagine that we will have to clean that. It costs me a couple of hours looking for the wrong bug when copying classes..... grgrgrgrg Stef

[Pharo-project] Pharo analog to Dolphin's "immediate objects"?

by Schwab,Wilhelm K

Hello all, Dolphin stores small integers and characters entirely in the header, and describes them as having "immediate" storage. Is there a similar concept in Pharo? I _think_ I can get around it by looking at other tests such as #isBytes, but I am still trying to decide whether they are simply named the same way or actually do the same thing. Bill

what would be good is to have a small discussion on the key and minimal features that could be added to Announcements, add some tests and code.

lukas could you deprecate the methods so that users get the time to update.

Levente what I would really love :) is if you could provide some extensions to the new version based on your experience. I think that Announcements are a bit limited right now. Then the core would be enhanced and we could clarified the license.

After lukas we can also read the blog and get some ideas for possible extensions.
