Oh, and it's worth noting that Dart is essentially the modern version of all this: a dynamic, class-based language, a fast VM that optimizes base on type feedback, and an IDE based on optional static type annotations. It's no coincidence, given that Gilad Bracha and Lars Bak were the initial designers of Dart.
