Hi,
Is there any specific reason why WorldMorph is not a subclass of
PasteUpMorph? The latter uses a variable to hold significant world state
and rest of Morphic use isWorldMorph to check the type before calling
methods.
I would have expected subclassing and double-dispatch to yield smaller
and cleaner code.
Regards .. Subbu
