[Pharo-dev] looking at the code of PasteUpMorph

[Stéphane Ducasse]

Hi

I think that it would be good to have 
        
        PasteUpMorph (a morph in which we can drop morph)
                subclass World (the world = a morph in which we can drop morph 
and that have a worldstate)

This would remove a lot of ifNil: everywhere.
