Highlights @[...] syntax properly inside quasiquote. + + - The third argument (the default value if a key is not found) can be omitted + when indexing hashes with the [hash key] syntax. It defaults to nil. + + - The dwim operator (and thus [] syntax) is even more Lisp-1 like. It + now has Lisp-1 namespace semantics for evaluating arguments + that are symbols. + + - A new operator called "op" as been added.
