Hi guys, Again one interesting topic for this weekend to discuss. David Nolen, a Lisp and JavaScript guy posted in his blog an article titled Illiterate Programming [1] where he said: "...Yet I think Smalltalk still fundamentally failed (remember this is a programming language originally designed to scale from children to adults) because *Objects are really hard* and no-one really understands to this day how to do them right...." He links to Alan Kay post [2] back in 1998 where he talks about problems with inheritance: "Here are a few problems in the naive inheritance systems we use today: confusions of Taxonomy and Parentage, of Specialization and Refinement, of Parts and Wholes, of Semantics and Pragmatics..." Let we concentrate on broader "Objects are really hard and no-one really understands to this day how to do them right" claim and not merely inheritance, please.
