Maybe Alain is right, remove accuny from core, and add also demo fonts for core? Or only the normal ones for core and then add in dev the rest?

Re: [Pharo-project] Proposal: adding 261 named colors

I think that this is good to clean it a bit anyway. Did you have a look at the other package too?

So if the trait has an #initialize method, then simply rename it to #initializeFooBar and send it from the class' #initialize method.
