Two questions/comments about the generated code: 1. #= ... self class = anObject class "should compare #species instead?" ifFalse: [ ^ false ]. ... Typically, I've seen #species instead of #class in the guard statement. Should we change it to that?
I doubt that it is important for domain classes. Because I never saw the user of #species which is not a kind of Collection. And for collections this refactoring is not valid anyway.
2. #hash ^ var1 hash bitXor: (var2 hash bitXor: var3 hash) Is this implementation always safe? It's what I usually hand roll based on what I've seen, but Andres Valloud wrote a whole (large) book on hashing, so I've always wondered if I was missing somethingâ¦
