Hi Marcel,
why do we need a redundant #initialize method for this? Wouldn't it have been enough to trigger #recreateSpecialObjectsArray in a postscript? Duplication hurts :-)

Hi Christoph. > Duplication hurts :-) Now think again about modularity and global state. ;-) Take the slot for "Alien" as an example, which I replaced in "FFI-Callbacks". Projects are free to switch between compatible classes as the VM will happily produce the new instances. While this may not be true for all slots in the special-objects array, it is still true for many of them. So, #recreateSpecialObjectsArray may be the actual issue here. Best, Marcel

Hi Marcel,
that's a fair point. :-) How can we get rid of Alien in #recreateSpecialObjects? Would it be okay to move it into something like "Alien initialize"? Or should #recreateSpecialObjects provide hooks/arguments to keep control of this central array? Von: Squeak-dev <[hidden email]> im Auftrag von Taeumel, Marcel
