So, to summarize: 1) Iterators are pointless because perl has foreach. (Which entirely misses the point of why you'd want to abstract the concept of iteration from the container. (Hint: try using foreach on a tree.)) 2) A bunch of trash talking about other languages type systems. (Incidentally, even when this was written, those criticisms were untrue.) However.. 3) According to the postscript, we should ignore the bogus parts I just mentioned above and just focus on the parts that are right. I'm guessing this is the "throw spaghetti against the wall and see what parts stick" school of persuasion, where you can just say a bunch of shit that's obviously wrong and then tell people to ignore those bits. So basically, the point of this talk is "go read Christopher Alexander's book"
