> I've had to re-implement dynamic language stuff in C++ many times to get acceptable performance. Performance in a certain sense isn't just speed of a single uncoupled module, but also the end-to-end seamlessness of a system. The higher level languages might 'waste' 300ms in every function call, but save perhaps years in development time. Also- architecting and developing medium-sized projects is not just the 'ENTERPRISE THING' anymore. A vastly greater number of people now have a-shot-at larger projects. So this creative freedom and technical UN-chaining also add to performance in a very in-direct way by allowing better minds to enter the game.
